Kenn's comment: Pretty good if I do say so myself. The plot really doesn't sit still for a chapter, so it keeps you on your toes in terms of trying to figure things out. While the story is about a genius, it's not like Death Note, where Light pretty much can handle everything because he's calm, cool and collected. The main character in this makes mistakes that a human would, and I've seen reviews saying that the manga sucked because of that. I bet they were hard core Death Note fans.
