The Fosters (American TV series)

The Fosters is an American family drama television series created by Peter Paige and Bradley Bredeweg. It premiered in the United States on June 3, 2013, on the ABC Family (later Freeform) television network and concluded on June 6, 2018. It followed the lives of the Adams-Foster family led by a lesbian couple, Stef Foster, a police officer, and Lena Adams, a school vice principal, who raise one biological son and four adopted teenagers in San Diego, California.

The first season received generally favorable reviews and particular acclaim for its portrayal of LGBT themes. It also earned two GLAAD Media Awards and one Teen Choice Award.

On January 3, 2018, Freeform announced that The Fosters would end after five seasons. It concluded with a three-episode finale, which also acted as an introduction to Good Trouble, the spin-off series starring Maia Mitchell and Cierra Ramirez.

Plot
This five season series follows the lives of the Adams Foster family who live in San Diego. The matriarchal heads of this family are police officer Stef Foster and her life partner Lena Adams, a school vice principal. Their multiethnic, blended family include Brandon, Stef's biological son from her previous marriage, and twins Jesus and Mariana, who were adopted as children. The series begins when the couple take in two foster children, siblings Callie and Jude Jacobs, whom they later adopt. The five children have rough time navigating adolescence because of poor life choices.

Also part of their lives is Mike Foster, Stef's patrol partner and ex-husband, and Brandon's biological father.

Most of the show takes place at the family's craftsman-style home in the quiet San Diego suburb of Mission Bay, and at Anchor Beach Community Charter School.

Main

 * Stef Adams Foster (Teri Polo) is Lena's spouse, Brandon's biological mother, and the adoptive mother to twins Jesus and Mariana. In the pilot episode, she and Lena also foster Jude and Callie, whom they later adopt. Stef is a police officer for the San Diego Police Department, where she works as a patrol partner with her ex-husband, Mike. She is known for having a strong personality with bold opinions but can also be loving and motherly. When Jesus goes missing one night, Mariana informs her parents how she fears Jesus is at their biological mother Ana's house since they recently got in contact and have been lending her money. Stef and Mike go to rescue Jesus only to discover that he is not there, and Ana's boyfriend, an abusive drug addict, shoots Stef, who is severely wounded before making a full recovery. Later, she officially marries Lena, and after having a mammogram, Stef receives a diagnosis of intraductal carcinoma. Because it is likely that the cells will become cancerous, she undergoes surgery.
 * Lena Adams Foster (Sherri Saum) is Stef's wife, step-mother to Brandon, and adoptive mother to Jesus and Mariana. In the pilot episode, the couple take in two foster children, Jude and Callie, whom they later adopt. Lena is the vice principal of Anchor Beach Community Charter School, the high school her children attend. She tends to be more open and reasonable, oftentimes when it comes to the children's wrongdoings but can be stern as well. She and Stef legally marry, and the discussion of Lena carrying her first child arises. Lena interviews for a promotion at work and reveals she is pregnant, leading the panel to question her ability to balance work and home. She later develops Pre-eclampsia, which leads to a miscarriage.
 * Callie Adams Foster (formerly Callie Jacob) (Maia Mitchell) is the adoptive daughter of Stef and Lena, adoptive sister to Brandon, Mariana, and Jesus, and maternal half-sister to Jude. In the pilot episode, the court places Callie in the Adams Foster home after serving time in juvenile detention for damaging her abusive foster father's property. Later, with Brandon's help, she goes to get her younger half-brother Jude (then believed to be her brother), who is still in the abusive foster home. Callie quickly develops a crush on Brandon before Jude becomes furious at her after seeing them kiss at Stef and Lena's wedding. Fearing the court will place her back into foster care, Callie attempts to run away, where she ends up eating food at a gas station without paying. This leads her into a temporary group home to counsel her actions and keep her away from Brandon. As time passes, Callie and Brandon hold back their feelings for each other. Callie's adoption is initially put on hold after the discovery that she and Jude do not share the same birth father. Later, Robert Quinn, who reveals himself to be Callie's birth father, approaches Callie. Robert introduces her to his family, and she quickly bonds with his daughter, Sophia. After Robert feels ready to turn over his paternal rights, Sophia tears up the paperwork, hoping Callie feels the same way about their newfound sibling bond, which appears to be the exact opposite. Stef and Lena officially adopt her following a prolonged battle with the justice system and a passionate speech to the judge.
 * Mariana Adams Foster (Cierra Ramirez) is Stef and Lena's adoptive daughter, Jesus' twin sibling, younger sister to Brandon and Callie, and Jude's older sister. Mariana is an intelligent teenage girl who likes to involve herself in whatever she finds enjoyable, particularly when she is social with her friends and gossips at school. She is also very proficient at coding and mathematics. Like many teenage girls, Mariana struggles with her self-confidence, heritage, and appearance, as seen when she dyes her hair blond to fit in. She dances, acts, and sings, forming her own dance team before becoming the lead actress in Brandon's senior project musical. Mariana initially supports her birth mother financially by selling Jesus' ADHD medication at school. Jesus confronts their birth mom to no longer contact Mariana, only to also rope in Brandon, which causes him financial and physical harm, for which she is apologetic. Later, Mariana hopes to change her image, joins the dance team, and takes a liking toward one of Brandon's bandmates. She is very close to Jesus, but they often tease each other.
 * Jesus Adams Foster (Jake T. Austin in seasons 1–2, Noah Centineo in seasons 3–5) is Stef and Lena's adoptive son, twin brother to Mariana, and sibling to Brandon, Callie, and Jude. He has ADHD and joins the wrestling team in an effort to offset the negative effects of his medication through the advice of Mike. Jesus loves his twin sister, Mariana, and the pair share resentment toward their biological mother. He is a womanizer at first, having a short string of romantic relationships and sometimes charming his mothers, including when he covers up for Mariana's wrongdoings. But he is now more respectful after getting back together with Emma. Jesus feels as though he has no involvement in Mariana's quinceañera preparations but later opts to be her escort in an effort to be at their birthday celebration. In the third season, Jesus temporarily resides at a boarding school for his high school wrestling team but returns after Callie's adoption. After he admits to his parents that he was taking steroids while away at boarding school, Stef and Lena no longer allow Jesus to participate on the wrestling team at Anchor Beach. Jesus later suffers a TBI after accidentally shooting himself in the head with a nail gun, which affects his personality and his academic performance.
 * Jude Adams Foster (formerly Jude Jacob) (Hayden Byerly) is the youngest Adams Foster child, he is Callie's half brother, and he is also Brandon, Jesus, and Mariana's adoptive sibling. Callie rescues Jude from their abusive foster father's house. As Jude settles into his new home, Mariana paints his nails blue and Callie tells him to wash it off but then learns to accept Jude's choices. At school, he quickly becomes friends with a kind-hearted boy, Connor, and as their friendship grows, Jude begins questioning his sexual orientation. When Connor's father suspects Jude's feelings, he forbids the boys from seeing each other outside of school. Jude slips into a phase of selective mutism, a social anxiety disorder where he does not speak entirely for a certain extent of time in fear of embarrassment, only to finally open up to Callie about his feelings. Jude and Connor kiss and begin dating, but Jude refuses to label himself as gay. After seeing how badly this affects Connor at an LGBTQ dance in season 3, he comes out as gay. At the end of the first season, Stef and Lena legally adopt Jude. Following Callie's own adoption, Jude admits he is in love with Connor, who returns the sentiment. After Connor moves to Los Angeles to live with his mom and because their long-distance relationship does not work out very well, they break up, and he later dates a new friend, Noah. Jude finally graduates from ABCC and gets into the College of Arts and Letters, UCLA. He and Noah maintain their relationship throughout their high school years, but break up when Noah goes to university, although they remain good friends.
 * Brandon Foster (David Lambert) is the eldest Foster child, biological son of Stef and Mike, and older adoptive brother to Jesus and Mariana, as well as to Callie and Jude. Brandon has an infatuation for Callie but after his biological mother and father place a restraining order against him, and despite he and Callie having sex the night before her adoption, they later resist further temptations to proceed with their relationship. Brandon also has a talent for music, excelling in piano, and is on the verge of entering a highly distinguished music program. After raising money to obtain fake IDs to get into a bar (as he is legally underage), Brandon is beat up by his dealer. Following his subsequent hospitalization, Brandon loses sensation in his hand, causing him to miss his spot in the music program. Still able to play the piano, he joins a band. In the third season, Brandon goes to the Idylwild band camp and competes to play at Disney Hall, where he wins the competition. During his senior year of high school, he receives an acceptance letter into The Juilliard School, his top choice in colleges and among the most prestigious in music and the arts. Later, however, Brandon is academically dismissed from ever attending college as a student discloses bribing Brandon to take his scholastic assessment test.
 * Mike Foster (Danny Nucci) is Stef's patrol partner and ex-husband as well as Brandon's father. He makes a number of appearances in the Adams Foster home, especially when it involves seeing Brandon. When searching for Jesus in the twins' birth mother's home, Mike witnesses Ana's boyfriend shooting Stef and, in turn, Mike fires at the shooter. The shooter is not armed when Mike shoots him, which causes conflict at his job as Stef keeps secret about it. He later learns that the money he gives his son for piano lessons is used to bribe Ana to lie in court so Mike does not lose his job. This only complicates the issue as the court abruptly determines that Mike is not guilty before Ana even has the chance to testify. Mike is also a recovering alcoholic, attends Alcoholics Anonymous meetings, and retains a live-in girlfriend, Dani, who helps maintain his sobriety. The pair break up when she is sent to prison for statutory rape with an already sober Brandon. Mike and Ana soon begin a romantic relationship and get engaged in season 5 and the two got married during the time jump; he also becomes the step-father of Bella. Mike was also the foster father to AJ Hensdale.

Following Nick's release from a psychiatric hospital, the court places a restraining order on him.

Fearing her safety is at risk, she subsequently calls Jesus before running away.

Conception
The Fosters was originally conceived by openly gay creators Bradley Bredeweg and Peter Paige who wanted to write a drama that reflected the "modern American family". After originally considering a story about two gay fathers, the pair decided the subject of two men raising a family had already been done on television and began to instead consider a story about two women. When asked about the concept of two lesbian mothers raising a blended family, Bredeweg stated, "We realized that there was a kind of a vacuum when it came to stories about women raising families. So we set off in that direction. Many of our own friends are moms raising biological kids. Some of them have fostered and adopted. Suddenly, we realized that we had a story here that hadn't been told on television before." Additionally, certain elements of the series which deal with the foster care system are said to have been inspired by a troubled childhood friend of Bredeweg, who struggled in the foster system before eventually being adopted in her senior year of high school.

Development
When developing the concept, Bredeweg and Paige were initially met with some resistance from Hollywood, with Bredeweg recounting, "[T]here were some people around us, some people in town who said, 'You know, it is just not going to happen. You are never going to sell this show.'" After completing the first draft of the pilot script, the team was introduced to Jennifer Lopez through a friend who worked at her production company Nuyorican Productions, which was looking to branch out into scripted television. When describing their initial pitch to Lopez, Bredeweg stated, "When we met with Jennifer, she really fell in love with it. The moment we had her, we knew that we had a force behind us."

Lopez's decision to become involved in the project is said to have been largely inspired by her late Aunt Marisa, Lopez's mother's gay elder sister who had faced discrimination during her lifetime due to her sexual orientation and was unable to have a family of her own. When discussing the show's concept, Lopez stated, "Although [the script] was about a non-traditional family and had some newer themes, it had some really basic themes as well about family and love and what's really important. And life can be complicated and messy sometimes and not simple. It gives a really good depiction of family in this day and age."

With Lopez on board, the team took the concept to several networks, including ABC Family, with Bredeweg recalling, "ABC Family was really receptive from the very beginning. Strangely, it felt a little like a match made in heaven. I mean, their slogan is 'A new kind of family.' We had a new kind of modern family, and it took off from there." On July 6, 2012, The Hollywood Reporter, among other sources, reported that Jennifer Lopez and her production company, Nuyorican Productions, were developing the yet-to-be-titled hour-long drama for ABC Family, with Lopez set to executive produce alongside Simon Fields and Greg Gugliotta, as well as showrunners and head writers Peter Paige and Brad Bredeweg.

Finally, the first televised promo appeared on ABC Family on April 19, 2013.

Casting
On August 23, 2012, sources reported that ABC Family had ordered a pilot for The Fosters, a series which would tell the story of a lesbian couple raising a "21st-century" multi-ethnic mix of foster and biological children. On September 24, 2012, it was reported that Teri Polo and Sherri Saum had been cast to star in the pilot as the two leads, Stef Adams Foster and Lena Adams Foster, respectively.

On February 6, 2013, it was reported that ABC Family had picked up the show, with production set to begin that spring for a summer 2013 premiere. The rest of the principal cast was also announced at that time, including Danny Nucci as Stef's ex-husband Mike Foster, David Lambert as their biological son Brandon Foster, Jake T. Austin and Cierra Ramirez as Stef and Lena's twins Jesus and Mariana Foster, and Maia Mitchell and Hayden Byerly as their foster children Callie and Jude Jacob.

When recounting the casting process, Bredeweg explained, "[W]e spent tireless hours trying to find the right person for each role. Then they all began to line up—it was like dominos—the moment we found our Lena, the moment we found our Callie, the moment we found our Stef, it sort of all started to line up perfectly for us." On April 11, 2013, TV Guide unveiled the first official cast photo of The Fosters.

In March 2015, it was announced that Jake T. Austin would be leaving the show. He tweeted: "I'm honored to have been a part of such a groundbreaking series, but I personally want to let you know that my time on the show has come to an end. Thank you for letting me be a part of your family, it's been a pleasure." It was announced three months later that Noah Centineo would replace Austin in the role of Jesus.

The three-episode finale will introduce a spin-off series centered around Maia Mitchell's Callie and Cierra Ramirez's Mariana.

Webisodes
On January 27, 2014, it was confirmed that ABC Family green-lighted a spin-off digital series of The Fosters, named The Fosters: Girls United. The five-part web series follows the residents of the Girls United home in a new country. Maia Mitchell, Daffany Clark, Cherinda Kincherlow, Annamarie Kenoyer, Alicia Sixtos, Hayley Kiyoko, and Angela Gibbs star in the series.

Critical reception
On the review aggregator website Rotten Tomatoes, The Fosters received an overall score of 98%. On Metacritic, the first season of the show holds a score of 69 out of 100, based on twelve reviews, indicating "generally favorable reviews".

While acknowledging its network was somewhat beholden to the "soapy" format its target demographic had become accustomed to, critics praised the series for its ability to appeal to adults and younger viewers alike, with Boston Herald critic Mark A. Perigard writing, "The show cannily plays to teen hopes and dreams [...] but there's story for the adults as well." St. Louis Post-Dispatch critic Gail Pennington echoed the sentiment, writing "Intelligent enough for adults, accessible enough for younger viewers and entertaining enough for both."

The series has garnered positive reception for its innovative portrayal of LGBT characters and themes. Entertainment Weekly critic, Sarah Caldwell wrote that "[s]eeing a lesbian, biracial couple on a family TV show is a big deal. [I]f you look at the demographics of most TV shows, it's easy to realize how important, and deliberate, this choice was." Philadelphia Daily News critic Ellen Gray wrote, "Stef and Lena [are] the kind of parents I've met more in real life than on television. I hope they'll be as welcome there as they seem to be welcoming." TV Guide critic Matt Rousch felt similarly, writing, "there's something refreshing about its unforced approach to redefining what a family looks like." In addition to its adult characters, the series garnered praise for its handling of 13-year-old Jude's questioning of his sexual orientation, with Hollywood.com citing Byerly's "heartwarming" portrayal when naming Jude to its list of "Favorite LGBTQ Characters on TV" in 2014. The LGBT advocacy organization GLAAD and gay-interest media outlet TheBacklot.com also commended the show's decision to introduce the character of transgender teenager Cole, portrayed by transgender actor Tom Phelan, in the second half of its first season.

In his review of the pilot episode, Variety's Brian Lowry criticized what he felt were formulaic elements, writing that what was distinctive about the series appeared to have been "extracted during the pitch meeting, indicating a show either built by committee or incorporating too many notes." Although acknowledging that Polo and Saum were competent actresses and that the show "had its heart in the right place", Lowry described the series as an "utterly by-the-numbers affair". PopMatters critic Maysa Hattab detected some of the same problems, writing "[T]he Fosters feel less like a family than a careful assembly of machine-tooled parts, as if the show were engineered for a focus group approved 'family drama' category", while conceding that the lead characters, Stef and Lena were "a likeable pair".

Controversy
On October 8, 2012, more than seven months prior to the series debut, the socially conservative One Million Moms organization, a division of the American Family Association, condemned Lopez and the show, encouraging audiences to boycott it. The group, which has routinely advocated against the depiction of same-sex couples in the media, stated: "While foster care and adoption is a wonderful thing and the Bible does teach us to help orphans, this program is attempting to redefine marriage and family by having two moms raise these children together." They issued the following statement:
 * Obviously, ABC has lost their minds. They haven't let up so neither will we. ABC's Family Channel has several anti-family programs, and they are planning on adding to that growing list. ABC Family has approved a series pilot from Jennifer Lopez's production company, Nuyorican, about a lesbian couple and their diverse family.

In response, ABC defended the television show, with ABC Family President Michael Riley countering that The Fosters merges perfectly with the network's "groundbreaking storytelling and iconic characters" and will feature "the same depth, heart, close relationships and authenticity that our viewers have come to expect". Other sources have also defended the show. Josh Middleton, a writer from Philadelphia magazine, called One Million Moms' statement "silliness" as well as "ridiculous" and said, "They obviously missed the boat on shows like Modern Family and The New Normal, which have been on air—and killing it in the ratings game—for a while now".
