Well, not all of them are bad. With most anime movies it's ok. But sometimes it really really bothers me. I noticed that it's worse, when I saw with Japanese voices first. I guess the characters and their voice are simply stuck in my head, and when I hear a different voice ... it just feels odd. Particularly as I think the Japanese language was really made for emotional and angry shouting. Which does happen quite a lot in animes after all . Uruse ! baka. Actually, the German one of One Piece is 'ok', at least compared to the English/American. I seriously ... don't know how they can stand it :/.
