I'd have to add my nostalgic love of Sailor Moon. I actually thought it pretty funny.
Digimon I'd also have to say didn't really have that bad of dubbing (well, for voices, I mean) as much as horrific botching with the editing and added jokes and stuff. I'd need to re-watch the dubs one day again to remeraber. lol I dunno, it must have been good enough for it to still be one of my most favorite animes to this day. I also thought Data Squad's version was dubbed quite good and even not as badly altered as the previous series had been.
I could maybe add some of the Transformers Unicron Trilogy. Good lord, I can't stand the dub of either Energon or Cybertron yet I still watched it! Armada, too. I think that one was easier to stand because the animation was at least still 2d and nice looking. Energon and Cyberton, though. THE PAIN. Oh wait, are we supposed to be enjoying the bad dub itself, or just able to enjoy the show despite it having a bad dub? lol Anyway, the Japanese version dubs though I actually could get through without wanting to stick a fork in my ears. XD It's not all of the voices, though, just some. But the dialogue is pretty awful, too. But I love Transformers...so. And yes I'm aware that those shows were made between the US and Japan, but they still have two separate version dubs, so I'm still counting it.
If I can remeraber anything else, I'll come back but for now that's pretty much all I can think of to mention.
