If you listened to a radio station which plays pop music and rock all the time, you wouldn't think that was what all music was like, you realise there's jazz, folk and classical as well, but that's not what you're into.
One of the problems is that people read stuff by a company such as TokyoPop, or the Shonen Jump releases and think this is manga style. Nope, it's what's popular, what you like, but it's still just a very limited range of styles in the first place.

Can you really say what the manga style is like?
