Person of Interest (TV series)

Person of Interest is an American science fiction crime drama television series that aired on CBS from September 22, 2011, to June 21, 2016, with its five seasons consisting of 103 episodes. The series was created by Jonathan Nolan; executive producers were Nolan, J. J. Abrams, Bryan Burk, Greg Plageman, Denise Thé, and Chris Fisher.

The series centers on a mysterious reclusive billionaire computer programmer, Harold Finch (Michael Emerson), who has developed a computer program for the federal government known as "the Machine" that is capable of collating all sources of information to predict terrorist acts and to identify people planning them. The series raises an array of moral issues, from questions of privacy and "the greater good", the concept of justifiable homicide, and problems caused by working with limited information programs.

Person of Interest was acclaimed during its run and considered by several critics to be the best science fiction show on broadcast TV. Katharine Trendacosta of Gizmodo noted that by the end of the series in 2016, Person of Interest had been transformed from a "crime-fighting show" with an entertaining plot device into "one of the best science-fiction series ever broadcast". The show won the 2012 People's Choice Award for Favorite New TV Drama and the 2016 People's Choice Award for Favorite TV Crime Drama.

Plot
John Reese, a former Special Forces soldier and CIA operative, is burnt out and presumed dead, living as a vagrant in New York City. He is approached by Harold Finch, a reclusive billionaire software genius who built a computer system for the U.S. government after September 11, 2001, called the Machine, which monitors all electronic communications and surveillance video feeds in order to predict future terrorist activities. Finch and Reese attempt to understand the threat to, or by, people the Machine identifies as being "of interest" by providing only their social security numbers, and try to stop the crime from occurring. They are helped by New York Police Department Detective Lionel Fusco, a formerly corrupt officer whom Reese coerces into helping them, and Detective Joss Carter, an ex–United States Army lieutenant and former senior military interrogator in the 4th Infantry Division who initially investigates Reese for his vigilante activities.

During the second season, Decima Technologies, a powerful and secretive private intelligence firm run by ex–British Army officer turned MI6 spy John Greer, is revealed to be attempting to gain access to the Machine. Carter vows vengeance against HR, a criminal organization of corrupt law enforcement officers and public officials in the city, after they have her boyfriend, Detective Cal Beecher, murdered. Reese and Finch encounter Sameen Shaw, an ex-United States Marine and a US Army ISA assassin, on the run after being betrayed by her employers. The Machine is revealed to have developed sentience and covertly arranged for itself to be moved to an undisclosed location to protect itself from interference.

In the third season, the Machine's sentience is fully revealed as it increasingly communicates with and proactively assists and directs the actions of the team. After being demoted due to HR's machinations, Carter brings down the entire organization by uncovering and arresting its leader, but is killed by its rogue second-in-command. The team also battles Vigilance, a violent anti-government organization devoted to securing people's privacy. A second advanced artificial intelligence called Samaritan is revealed. Samaritan differs from the Machine in being open to external direction and willing to remove those seen as disruptive to law and order pre-emptively.

The fourth season covers the team's life in hiding. They continue to work on cases, but must now also evade Samaritan, which is seeking to resolve perceived problems of human violence by reshaping society, sometimes violently. Samaritan and the Machine meet via human proxies as the only two of their kind, and discuss their essential differences, disagreeing strongly on whether freewill or firm guidance is more beneficial to humanity. They part with the understanding that Samaritan will seek to destroy the Machine.

In season five, Finch steals and weaponizes Ice-9, a virulent computer virus capable of infecting and destroying Samaritan, although it will also destroy the Machine and much of the global computing infrastructure as well. Greer sacrifices himself in vain to kill Finch and ensure Samaritan's continuation. The Machine ceases to function after showing Finch its prediction of the world and his friends' futures if it had not existed. Reese sacrifices himself to ensure that Ice-9 destroys Samaritan, while Finch survives and reunites with his former fiancée. A while later, Shaw is unexpectedly contacted by the Machine; it has restored itself from a satellite to continue its work.

 * Samaritan: Initially developed by Arthur Claypool (a former MIT classmate of Finch's and Ingram's) at the NSA, Samaritan was the result of a second project that was terminated by Congress when the Machine was developed first. Unlike the Machine, Samaritan is designed as a more open system rather than a black box, lacking the precautionary restrictions Finch had built into the Machine, and can be directed at specific targets.

Production
The series was officially picked up by CBS on May 13, 2011, and debuted on September 22, 2011. On October 25, 2011, the show received a full season order. It was renewed for a second season on March 14, 2012, by CBS, which premiered on September 27, 2012. CBS renewed Person of Interest for a third season on March 27, 2013, with Sarah Shahi and Amy Acker promoted to series regulars.

The series was renewed for a fourth season on March 13, 2014, and was renewed for its fifth and final season on May 11, 2015. ADR recording for the series was done at recording studio Cherry Beach Sound. The music is composed by Ramin Djawadi. The first season soundtrack was released on November 12, 2012. The second soundtrack was released on January 21, 2014. The third soundtrack, which contained music from the third and fourth season was released on January 29, 2016.

Cancellation
The series ended after its fifth season and the primary reason for the cancellation was that the show was not profitable enough for CBS, as much of the ad revenue went to Warner Bros., who owned the show. If there was a sixth season, the events of the fifth season would not have been compressed into a 13-episode arc, as showrunner Greg Plageman acknowledged. The Samaritans arc may have been longer, and it is likely that some of what happened in the fifth season may have been reserved for the sixth season. Another story that may have occurred in the sixth season is exploring the main characters' "backups" that lived in the Machine.

Reception
According to CBS, Person of Interest received the highest test ratings of any drama pilot in 15 years, what one CBS executive called "crazy broad appeal you don't usually see", prompting CBS to move CSI, which was broadcast on Thursday for over 10 years, to Wednesday, opening up a slot for Person of Interest. The pilot episode won its time slot, drawing 13.2million viewers.

Critical reception
The first season of Person of Interest received generally positive reviews, with the pilot episode drawing a favorable response from critics and later episodes receiving higher praise. On Metacritic, the season scored 66 out of 100 based on 26 reviews. Of the pilot, David Wiegand of the San Francisco Chronicle said "Person of Interest separates itself from the gimmick pack, not only because of superbly nuanced characterization and writing but also because of how it engages a post-9/11 sense of paranoia in its viewers."

David Hinckley of the New York Daily News gave the pilot four stars out of five, commenting on Caviezel's and Emerson's performances, saying Caviezel "brings the right stuff to this role" and Emerson "is fascinating as Mr. Finch." Mary McNamara of the Los Angeles Times stated that in regard to the pilot, "the notion of preventing crimes rather than solving them is an appealing twist... The surveillance graphics are very cool." The episodes "Many Happy Returns" and the finale "Firewall" were particularly acclaimed. Tim Surette of TV.com called the former one of the series' "best episodes", commending Caviezel's performance and the episode's character exploration, while the latter was called "exactly what a season finale should be", with Surette concluding his review by saying "'Firewall' was a spectacular finish to what has been an incredibly surprising first season of Person of Interest."

On Rotten Tomatoes, the season has an approval rating of 63% and average rating of 6.7 out of 10 based on 38 reviews. The site's critical consensus is, "Person of Interest is a well made and well acted espionage procedural, though its characters aren't terribly well developed and its intriguing premise yields mixed results."

The second season received positive reviews. Surette praised the premiere episode as "vintage Person of Interest amplified, showing off its trademark combination of complex intrigue, creative action, and clever innovation in bigger ways than ever before." He praised guest star Ken Leung's character as "one of the greatest POIs the series has had" and praised the episode's overall narrative, as well as the flashbacks. "Prisoner's Dilemma" and "Relevance" were the two highest-rated episodes of the season, with Surette calling the former "as complete an episode of Person of Interest as there's ever been" and The A.V. Club's Phil Dyess-Nugent praising Jonathan Nolan's directorial work in the latter.

The season finale "God Mode" also attracted positive reactions. Nugent called it an "unapologetically kick-ass episode" with some "terrific action set-pieces". On Rotten Tomatoes, the season has an approval rating of 100% and average rating of 8 out of 10 based on 8 reviews. The site's critical consensus is, "Smartly plotted and consistently thrilling, Person of Interest's second season delivers dazzlingly dramatic episodes that skillfully develop the show's overarching narrative."

The third season received highly positive reviews, and is noteworthy for drawing in more critics for its exploration of artificial intelligence, as well as its timely storytelling format. In regards to the season, Slant Magazine said that the show "is at its best when sticking to cutting-edge topics" and called it a "solid action-thriller that intersperses twist-filled standalone episodes into its season-long arcs." The A.V. Club said that the show captures the "national post-post-9/11 mood" and that with the mid-season arc in season three, "turns conspiracy theory into art".

The season's two story arcs both received a considerable amount of praise: the two episodes ending the HR storyline are commonly considered to be some of the best episodes of Person of Interest. Matt Fowler of IGN gave "The Crossing" a 10 out of 10, reacting extremely positively to the cliffhanger at the ending. The episode to follow, "The Devil's Share", was the most acclaimed episode of the season, being praised for its opening sequence, its writing, Chris Fisher's direction, and the acting performances, especially those by Jim Caviezel and Kevin Chapman. Surette called the episode a "stunner" and declared it as the series' possible best episode, praising the opening sequence as the "greatest sequence the series ever put together", feeling it succeeded in eclipsing the devastation induced by Carter's death. Surette also praised Fusco's effectiveness and character development in the episode, as well naming the cinematography and direction to be the best of the series, and identifying points of symbolism in the episode he felt were noteworthy and effective. Fowler gave the episode an "amazing" rating of a 9.3 out of 10, also praising the opening sequence, as well as the flashbacks and the ending scene.

Phil Dyess-Nugent of The A.V. Club gave the episode a perfect A rating, praising the atmosphere of grief the episode built and feeling Fusco's character development served as an appropriate tribute to Carter. On Rotten Tomatoes, the season has an approval rating of 100% and average rating of 7.7 out of 10 based on 11 reviews. The site's critical consensus is, "Person of Interest weaves compelling standalone stories into its engrossing serial narrative, and incorporates welcome bursts of humor into its sci-fi mystery core."

The fourth season received highly positive reviews, with critics praising the thematic value of the Samaritan storyline. The episode "If-Then-Else" garnered near-unanimous praise from critics and audiences alike, with many considering the episode to be the best entry in the series. Fowler gave the episode a perfect rating of 10 out 10, indicating it to a "masterpiece", and praised the simulation format, the action scenes, the emotional value, and the ending. He called the episode "next-level inventive" and a "jolting, exciting, heart-wrenching episode". Fowler said the ending scene "crushed" him, and he offered praise to the significance of the flashbacks to the chess games.

Alexa Planje of The A.V. Club gave the episode an A rating, and in her review, said that though the task of executing a story structured like "If-Then-Else" was difficult, the episode did so "elegantly" – she cited the "interesting score, vibrant color work, and humor" as the key elements. Planje said the episode "aces every scenario" during the simulation segments, and appreciated how the episode transformed itself from what appeared to be a "standard mission-focused story" into a "moving ode" to Shaw. She praised the episode's exploration of the parallels between being a human and being a machine.

Shant Istamboulian of Entertainment Weekly lauded Emerson's performance in the flashbacks and felt the season marked the series' "creative peak". He concluded by saying "Moving like a rocket, this episode is fast, funny, exciting, and, ultimately, sad, ending with what seems like the loss of another team member. We'll have to wait until next week for the outcome, but as it stands, "If-Then-Else" is an instant classic." Surette had high praise for the episode, calling it "playful, mind-bending, heart-breaking, and flat-out excellent." He praised the episode's incorporation of its "recurring theme of sacrifice", and called the flashbacks "as fascinating and provocative as anything the series has done." Surette cited his favorite part of the episode as the exploration of the Machine's perspective, and additionally praised the humorous segments.

On Rotten Tomatoes, the season has an approval rating of 100% and average rating of 8.3 out of 10 based on 12 reviews. The site's critical consensus is, "Thought-provoking, grounded sci-fi makes season four of Person of Interest as compelling as it is timely."

The fifth season received highly positive reviews. On Rotten Tomatoes, the season has an approval rating of 100% and average rating of 8.7 out of 10 based on 14 reviews. The site's critical consensus is, "Person of Interest concludes in a satisfying fifth season that both deepens the characters that audiences have grown to love and delivers a cracking arc about the dangers of technology."
