Critical response
Season 4 received highly positive reviews and is often considered to be the best season of the series. Michelle Zoromski of IGN gave Season 4 an overall rating of 8.5 out of 10. Michelle stated, "This fourth season seemed to settle down the chase for the titular mother. While Ted was busy dating Stella, the gang settled into many stand alone episodes which were every bit as entertaining as episodes devoted to Ted's love life," later going on to say, "A stellar Robin-Marshall episode, titled "Little Minnesota," makes it clear that these two do not get enough screen time together. With Robin homesick and unemployed (and at risk of being deported), this pairing brought out the best Robin Sparkles reference of the season, when Marshall leads a rousing karaoke version of "Let's Go to the Mall!"
