my biggest dissapointment, and im sure im not the only one out there who felt this way, nolan screwed up joker to an extent. not TOTALLY, but lets just say he changed joker about as much as burton changed the penguin. there were times where he just looked TOO much like a normal guy, and it was hard to watch. despite the lone "first appearance", joker was never a normal guy who puts "war paint" makeup on, he got dumped in chemicals and got perma white. in fact, it made more sense for him to be laughing all the time, the chemicals MADE him even more insane then he was before and it made him laugh uncontrollably. then joker would use the chemicals that made him joker, and apply as a weapon that would make ppl "die" with uncontrollable laughter. THAT is joker.
ledger did none of that stuff, he was like some normal guy who didnt appear to be artistic or have any kind of style in any way. a gun and a knife. woohoo, thats only part of what makes joker "joker". jack had guns....but he also had the rest of the joker gear, like pop guns, laughing gas, hand detonators, etc. he had all the gags that are familiar with joker. ledger had NONE of that stuff. which is why i believe that jacks joker is still THE best joker. period. you can say what you want, but thats my opinion and i aint changing it.
