Dexter

This show is simply a work of genius. Dexter is an anti-hero, a character with a "dark passenger", a man who feels the need to kill and has very little emotion. He is brought up by his step father, a police officer who instills him with a 'code' to follow - he can only kill those who only deserve to be slain, i.e. those who escape justice. When he's not dishing out his brand of 'justice', Dexter moonlights by day as a forensic blood splatter expert, the perfect cover, whilst also trying to conduct a "human" relationship with his girlfriend Rita and her two children. The first two seasons where some of the best TV I have seen since Lost began, but unfortunately season 3 seems to be dropping in quality due to a weaker storyline. I will continue to stick with this show for now, as it has been a breath of fresh air, but it could be closer to jumping the shark than not!
