I'm not sure what the exact source is for these statements (they're most likely apocryphal), but I've read that when shown clips of the English dub, Japanese viewers vastly preferred Johnny Yong Bosch over Jun Fukuyama. Interpret that as you will, though as I said, those statements are most likely apocryphal; if someone with better Google-fu than me can locate a reliable source for them, however, then go right ahead. In any case, makes one wonder, doesn't it?
