I've been a fan of Person of Interest since it started. It was a little shaky at first, but ultimately enjoyable and has only gotten better. The intricate backstory has been fun to piece together and pick apart and the cases have been very interesting. Jim Caviezel and Michael Emmerson are great together and one of the joys of its second season has been growth of the cast to include Ken Leung, Amy Acker and Sarah Shahi in recurring roles.The end of season two leaves season three in a new position as The Machine is now entirely free to do what it wants. It's a very intriguing plot to see play out as several people will attempt to control it. There's the government, Decima and of course our POI team. Shahi and Acker have also become regulars for season three, adding much more tension to discover The Machine's secrets. I can't wait to see what comes next in this growing series.
