I'm not really seeing the epic badness of these. The guy just sounds like your typical generic teenage hero type. The girl sounds weird, but the dialogue suggests she's probably supposed to be a screwed-up alien magic robot doll or something, so it's intentional. As Sho Nuff says, most of the remaining strangeness is more about the (original) pacing of the cutscenes than anything in the English voices. It's not a patch on any of the classic bad localizations of the 90s in any case. (also, it's just tediously bad, not hilariously bad like SO4)
