I have'nt seen much Dragon Ball(it's one of those franchises on the top of my list, though) but I have a watched a few dubbed and subbed episodes, and, even though I did'nt think the dub was too bad, I just thought the sub was better. I mean, if you watch and like the dub, than the sub is like the same show with better editing. (I don't have this opinion often; as I've said before, I'm mostly a dub guy.)
Ooo, ooo, I've got one! Any show that was originally two or more different shows in Japan, but got fused together for an American release (it happened more often than you'd think).
