Although the hit CBS drama "Person of Interest" has been renewed for a fifth season, it is in what most people call the "danger zone," according to Deadline. Basically, what this means is that the show has been given a partial order of only 13 episodes for next year, and it is not even on the fall schedule.

Most broadcast network TV shows consist of a 22-episode season, with some getting as many as 25. Of course, there are some instances where that number may vary, especially on cable TV and streaming TV shows, but most stick to the formula for broadcast networks.

Season 5 has been given a mid-season debut to start in 2016. And if other shows that have been given that "partial order" treatment is any indicator, then this could very well be the last for "Person of Interest."

Deadline noted that last year that "The Mentalist" was also given a partial order for the upcoming year. It was only a few months later that it announced that it had been canceled. This may be due in part to the show being just strong enough to get the small order as a way to say goodbye to its fans, or to conclude some of the many storylines that are attached to it.

If "Person of Intersted" ends in 2016, that means that at some point during the season, Reese (Jim Caviezel) is going to die, as foretold on the pilot episode when it debuted on CBS back in 2011.

The September 2011 debut of "Person of Interest" was a breakout hit for CBS and became the network's Thursday anchor show. The show then moved to Tuesdays, where it did all right in the ratings, but obviously it was not strong enough to for full Season 5 episode order.

The series is one of the rare shows on CBS that is not owned by the network. It is actually owned by Warner Bros. This makes some wonder if the show will be transplanted to another network, such as CW or maybe make its way to a streaming platform.

The Hollywood Reporter notes that Denise Thé has signed on as executive producer for Season 5 of "Person Of Interest."
