Michael C. Hall as Dexter.
He can't control his urge to kill. So he channels it toward the common good... by only killing the bad guys. A modern day vigilante, Dexter is a blood splatter expert by day, and a serial killer by night. In the first season of this new Showtime drama, we saw Dexter struggle to maintain a facade of normalcy as he tried to imitate the emotions he can't feel. Now, in the second season, Dexter finds himself having to help the police department track himself down for one of his own murders. Campy and full of twists, Dexter is definitely worth a Sunday night -- or a Wednesday afternoon, as we've got Michael C. Hall here to tell us all about it.
