Dexter: Season Five [Blu-ray] (2010) for $26.99

When executive producer/showrunner Clyde Phillips exited Dexter at the end of the fourth season, he left the remaining cast and crew with a puzzle worthy of a cackling supervillain: not only find a way to top John Lithgow's stunning performance as a Big Bad, but also somehow rebuild the main character's life after the season finale's devastating ending. While this subsequent season definitely shows some signs of early fumbling, it sports more than enough twisted drama to keep viewers firmly on (or behind) the couch.
