Personally, not only do I not like Pretty-Boy Ledger playing The Joker, because he looks too young--and would make a better Robin or Nightwing. But, I don't like the idea of THE JOKER in the sequel, period. One reason is, The Joker is too ubiquitous as Lex Luther is in Superman's methos (in various mediums) it's a 'been there, done that' kind of thing.
I also hate the idea of Two-Face (rumored) to be in the film, none of these characters can fight Batman. And after the blurry, choppy and lack lusting fight scenes in BB, I was hoping for a physical challenge that would bring about the greatest fighter in comics within in The Dark Knight.
I was hoping for both KILLER CROC (disturbed and animalistic), whom would surely bring out every ounce of fighting technique--that Batman has learned to take him down. And MR. FREEZE, who's not only highly intelligent, but can also give Batman a go with the physical fights, among other things. Both characters also call for a lot of detective work into their backgrounds.
This is what I wanted to see in THE DARK KNIGHT. I just hope most people don't feel the same way, or we could have another Superman Returns on our hands. Lex Luthor being the main villain, was just one of the things that put a nail in the heart of that film.
