Storyline

Meet Dexter Morgan. By day he's a blood spatter pattern expert for the Miami Metro police department. But by night - he takes on an entirely different persona: serial killer. But Dexter isn't your average serial killer as he only kills people who fit a very prolific and precise "moral code" taught to him by his late father Harry (he didn't kill Harry, honest), and developed very thoroughly throughout each kill. While dealing with his daily activities and his boss, Sgt. Doakes, the one man who may or may not know the truth about his after-hours activities, he is given a friendly message by a guy referred to only as "The Ice Truck Killer" - a crime scene where there is no blood. This shocking discovery turns Dexter's world completely upside down. The Ice Truck Killer wants Dexter to play his game and Dexter is very eager to take on this cat-and-mouse chase throughout Miami.

HBO Actors, HBO Directors, HBO Writers, and Showtime's willingness to take risks that HBO might not see as profitable these days (Carnivale + Deadwood R.I.P.) make for a killer combination in "Dexter," the new Sho Comedy/Drama about a Serial Killer Killing Serial Killer (you read right). In my opinion, Showtime has always had a hard time producing an original series that's truly original and good, so it's incredibly refreshing to see the network pull such a "Hail Mary" move and come out on top. "Dexter" is, without spoiling anything, an excellent vehicle for Michael C. Hall, and explores the inner monologue of a Serial Killer in a way that has never been approached before without seeming too predictable or hokey. Watch it and you will not be disappointed. You'll even want to watch the next episode, which says a lot considering the network. I just hope they don't screw it up.
