Person of Interest (2011)

Come for Michael Emerson, stay for the best-kept secret on this list. Lost's Ben Linus plays Harold Finch, a reclusive billionaire whose surveillance machine predicts violent crimes, in a series created by Jonathan Nolan with J.J. Abrams producing. Flashbacks slowly reveal how Finch and his partner became who they are, and Emerson has said its reveals come faster than Lost's did. It starts as a weekly crime procedural, which puts some Lost fans off. Stick with it: the larger story about the machine takes over, and the five CBS seasons build to a finished ending.
