Well, original Yugioh is really the ONLY place where the voices seemed to somewhat fit. 5D's however, is a different story. Tristan was probably the worst VA there, and since he was a side character with rarely any action, it wored out. but when that VA is doing the voice of the main protagonist... Weve got biiig problem.
Plus, who was saying anything about voices?
America and the dubbing of Anime has ALWAYS had problems, so Voices are the LAST thing I judge. Its everything else that matters. like, do they censor anything? cut anything? etc etc. Now, with other companies, there usually is no real issue there, so it just goes on to the voices. But with 4kids...
