Us Rating: ***

Air Date: Sunday 10/2

In the gory drama's return, bloodthirsty avenger Dexter Morgan (Michael C. Hall) attends his high school reunion — so he can off a jerk who murdered the only girl who was nice to him 20 years ago. Dex's macabre enterprise is played with more humor than usual (he's even seduced by a faded-cheerleader type, allowing Hall to show off his comic chops). Never fear: The chilling undertone remains, and his newest rivals in serial killing -- a creepily religious pair played by Edward James Olmos and Colin Hanks -- will have viewers squirming. (Showtime, 9 P.M.)
