Well, it has good characters, they aren't boring. The storyline is good too. It has good action, and it has a good balance of funny things and serious things, although mostly serious. It has a good opening, if that means anything. Lol. Its kind of sad. I don't really know how to explain it, its just really amazing. You'd just have to watch it for yourself. From what I remember theres only 13 episodes. It is my all time favorite anime.
