Before 'Person Of Interest" Season 5: WATCH Jim Caviezel, Michael Emerson On WGN America!

Before Season 5 of Person of Interest premieres in 2016 on CBS, watch the sci-fi crime thriller from the very beginning. Watch episodes from the first to fourth season on WGN America, as Finch (Michael Emerson) and Reese (Jim Caviezel) fight to save lives in the new "Prime Crime" lineup.

In our finale recap, we last saw Sameen Shaw walking away willingly with Samaritan's agents, possibly because she was brainwashed. As Samaritan's agents took out Elias and Dominic, Greer's men put a bag over Control's face and took her hostage. As Pink Floyd's Welcome to the Machine started playing, Finch walked out, with no gun, alongside Reese and Root as they started shooting down Samaritan's agents.

According to Deadline, the WGN America features Elementary stars Johnny Miller and Lucy Liu and POI's Emerson and Caviezel. Both shows are facing off in a test to determine who's the better twosome and why. The two procedurals join Blue Bloods in the cable channel's Prime Crime lineup this fall.

From the beginning, watch as billionaire Harold Finch and ex CIA operative John Reese prevent violent crimes before they happen. With the help of The Machine, they managed to save innocent lives right when their numbers popped up. Before stealing the show as Cookie, check out Taraji P. Henson as Detective Carter.

One of the best episodes, in this critic's opinion is the episode is Relevance. In the episode written and directed by showrunner Jonathan Nolan, viewers were introduced Sameen Shaw (Sarah Shahi). Let's not forget Amy Acker, who started out as the big bad and turned into the anti-heroine know as Root. 

Don't forget to check out the cast and crew of POI as they take over San Diego Comic Con on Saturday, July 11, at 5:15 p.m.-6:15 p.m. in Room 6BCF. What will they dish on the upcoming 13 episodes that will air midseason? Could these last 13 episodes truly be the end?

Episodes of Person of Interest  and Elementary air on WGN America in the fall.

Readers, are you excited to see POI on WGN?
