The fourth season of the American television series Person of Interest premiered on September 23, 2014. The season is produced by Kilter Films, Bad Robot, and Warner Bros. Television, with Jonathan Nolan, Greg Plageman, J. J. Abrams, and Bryan Burk serving as executive producers and Plageman serving as showrunner.
The series was renewed for a fourth season in March 2014[1] and stars Jim Caviezel, Kevin Chapman, Amy Acker, Sarah Shahi and Michael Emerson. The series revolves around a team led by a mysterious reclusive billionaire computer programmer, Harold Finch, 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, as well as detecting all lesser crimes, known as "irrelevant" crimes. The focus of the season involves the team's fight against Samaritan, a mass surveillance system that aims to destroy the Machine.
The season premiered on September 23, 2014, on CBS and ended on May 5, 2015. Viewership for the season averaged 12.22 million viewers, ranking as the 21st most watched series of the 2014-15 television season.[2] The season received highly positive reviews from critics, with the writing, performances and Samaritan's thematic value garnering praise. One of its episodes, "If-Then-Else", received near-unanimous praise from critics and audience and was deemed one of the series' best episodes. In May 2015, CBS renewed the series for a fifth season, which would be later announced to be the final season.[3][4]
