The CBS sci-fi crime drama Person Of Interest has been on the air for five years, with the first two seasons being a ratings bonanza for the primetime network. However, the last two seasons saw a fairly decent ratings decline after the show's move to Tuesday nights, even though the reviews continued to get stronger each season.
The series did receive a fifth-season renewal shortly after the fourth season finale, which didn't shock anyone — but the details of the renewal did. CBS chose to only give the show a 13-episode order for the newest season, unlike the previous 20+ episode orders per season. In addition to the short season, CBS also announced it would be a midseason premiere, which many took as a sign that the network might have been losing faith in the series and was looking to wrap it up.
Now, CBS has set a premiere date for the fifth season, and has also announced that it will be the final season for the J.J. Abrams and Jonathan Nolan series. The cancellation announcement came just a few hours after the May 3 premiere date for the fifth season.
J.J. Abrams, executive producer of the show, admitted at the Television Critics Association winter press tour that "my guess is this is the final season," and that the creators have written a finale to act as a series finale, but that if they have a "miraculous performance," they can adjust things to keep the show going.
The absence from the fall 2015 schedule and the short episode order was the beginning of the flame of cancellation speculation, and the news of star Sarah Shahi snagging the lead role in CBS's upcoming adaptation of the Nancy Drew book series seemingly added the final fuel to the flame to burn the POI house down.
In addition to the short season, CBS will burn the series off quick by premiering two episodes per week, starting May 9, with an episode premiering every week on Monday and Tuesday nights at 10 p.m.
