Hehe, someone just posted this on another forum and it made me laugh…
Simple answer, the only reason why Onepiece did so horrible here in america, because it was'nt just because of the butchered Dub,but also because when it was first shown on 4Kids tv,not many people hardly knew about the Dub,because not many older people wake up in the morning to watch saturday morning cartoons,when most people sleep in on saturdays,because of this, it lost ratings which is why it moved to Toonami to try to help boost it's ratings.
There you have it, One Piece failed in America because Americans sleep in on Saturdays!
