Naruto would be ruined if it was made by a Hollywood studio. The ending would make no sense, the characters would be completely different than those from the last two parts, there'd be overtones of the abusive American meta-culture that would place strong women like Sakura into roles like a house-wife to an abusive idiot, place Naruto in a loveless relationship with a woman he never really loved or knew, and any black character would speak in ebonics for no reason beyond "Hey, they're black, better make them gangstah!", and even worse, there'd stupid names like "Bolt" or "Salad" for some of the random bastard off-spring of the main characters.
Pffft, who'd want to see that happen?
