I'm a big fan of revenge works which is probably why I like Dexter so much. He's a loveable, funny, dark, guy who you can't help but like despite his habit of serial killing. The acting is superb all around. The ensemble cast is brilliant. The writing is crisp. If you're squeamish, Dexter is probably not for you. The tension builds well. There are twists and turns in season 1 that most will never suspect. It's got laughs, mystery and great characters. A very good show all around.
