Probably one of the best works of fiction ever, not just anime. Death Note accomplishes a ,kind of complexity that many other shows won't even attempt. Playing out like a game of chess, the two protagonists constantly try to outsmart each other. 10 years down the track this is still one of the most powerful and clever shows I've ever seen.
Undisputedly one of the best anime shows of all time, Death Note was a revolution. If you haven't seen it already, you either hate anime or are have been living under a rock. Welcome to the world, it's time you watched Death Note!
