"Hart of Dixie" was not renewed for a fifth season due to low ratings, says Entertainment Weekly. During the 2014-2015 season, the series averaged only 1.6 million viewers and a 0.6 rating in the 18-to-49 demographic.
Leila Gerstein, the creator of the show, treated the "Hart of Dixie" March 2015 finale as the show's final episode. The show's stars viewed this episode as the finale as well, so followers were unsurprised by the cancellation.
"Hart of Dixie" premiered on The CW on September 26, 2011. The show featured Rachel Bilson as Dr. Zoe Hart, an aspiring heart surgeon from New York who becomes a general practitioner in the fictional town of Bluebell, Alabama. The first three seasons were 22 episodes each, while the fourth and final season was 10 episodes.
Other principal characters include Jaime King as Lemon Breeland, the daughter of the town doctor, who serves as a rival and foil to Zoe; Cress Williams as Lavon Hayes, a former NFL linebacker who serves as the Mayor of Bluebell and owns a pet alligator named Burt Reynolds; and Wilson Bethel as Wade Kinsella, Zoe's bartender neighbor who becomes a recurring love interest for Zoe over the course of the show.
