Person of Interest (10/9c, CBS): Following the cataclysmic events of last week, and with only three episodes remaining of this powerfully distinctive thriller, Finch (the great Michael Emerson) stops being team player to go solo, now that his war against Samaritan has become even more personal. As he mulls going further to the dark side to take down the AI that threatens his beloved Machine, the remaining survivors head to Washington, D.C., to protect the actual Commander in Chief when the President’s number comes up, suggesting yet another conspiracy for our underdogs to unravel. Very strong final season
