Eh, I personally despise it, but I guess it's probably good for the youngsters. I read some of the manga when it first was released, (before it was brought stateside officially), and liked it at first, (I was young and stupid)...but bleh, I've grown out of shonen. I really liked DBZ when I was little, (which I actually don't feel ashamed for...at least I wasn't obsessed with the Pokemon anime, thank god.), and I enjoyed Bleach up until the end of the first arc, (after which it spiraled into utter mediocre, which may in fact be an extreme understatement).
Maybe some people enjoy shonen past twelve, and that's fine, but no...not for me.
BELIEVE IT!
