I guess I just dont understand, personally, why this totally changes the character for some people. I could understand if he wasn't permawhite and also acting wildly strange or different from what most people recognize as the Joker, but by all accounts, this interpretation is closely related to the original Joker conceptually, why is it such an issue? I've said this before, but Batman has never appeared in any of his movies with spandex on, his origin was completely tinkered with in B89, then re-imagined again in BB, neither of which is what happened in the comics, why was all of that ok and not this?
Nolan had a specific vision from the time he started this franchise, going into it I expected even more to change concerning the Joker. No, no matter how many times you guys try to explain it, your not falling into chemicals and coming out bleached white with green hair, it's not gonna happen. Yes its a comic book, but Nolan decided to ground it in some sort of reality, doing that not only changes the Joker, but pretty much eliminates a bunch of batman's rogues gallery as well, I'm sure we wont be getting Mr. Freeze or Killer Croc anytime soon. That being said, what we are getting, is pretty darn good, maybe if you just wait to see the movie, your attitude towards this whole situation may change...
