I’m not sure how many of OP’s contributors are into the Showtime series, but I should think a recommedation from this contributor would suggest at least a look (or more). I will admit, however, that it took more than one episode to get hooked.
Centered around a police department’s forensic blood splatter analyst, gore is the basis for the show. But, oh! It’s so much more. The series is based on Darkly Dreaming Dexter, a novel by Jeff Lindsey… Something I didn’t know, myself, about the show. Dexter Morgan, like previously mentioned, is a blood splatter analyst in Miami, Florida played by Michael C. Hall. He’s a sociopath and was raised by a fellow Miami police officer that took him in when he was a child, and seeing said sociopath tendendies, taught Dexter to channel them… As a serial killer.
