Blood and guts is paying off for Showtime. "Dexter," Showtime's top-rated and critically acclaimed series, is getting a second season: 12 new episodes, in 2007. The series, based on the novel "Darkly
Dreaming Dexter," follows a Miami forensics expert who is also a serial killer--although of the avenging angel variety. It stars Michael C. Hall of "Six Feet Under" fame.
