I see your point, although I disagree with it, but in the end, the overall quality of the film and how the Joker's role aided to it will be the ultimate deciding factor for me on the presentation of the Joker, not so much his makeup, which I took the smeared effect to mean that his "transformation" in the chemical bath wasn't perfect, it left blotches and smears and made him an extremely ugly clown.
Btw, if you want to talk about original Joker's, the original Joker was not a psychopath, he was "merely" a homicidal maniac, then he pretty much became a petty thief, then was revived as a psychotic homicidal maniac, and Batman's worst enemy. I'm not much into comics anymore but when I was a little lad I read everything my friends bought, and my dad collected (and mom later accidentally destroyed
). Which is why a lot of these super hero movies have been disappointing (or have disappointing moments like in Xmen 3 Xavier and Juggernaut don't even look at each other despite being stepbrothers, and they made Juggernaut into a mutant when it's a gem inside his helmet that grants him powers but I still enjoyed the movie)
I think the new Joker embodies what the "popular" (and best) idea of what who the Joker is, mantidor does have a fair point about him being too straightforward, I would have preferred the introduction of the Joker started with his famous marbles. "Oh look marbles" (everyone laughs until...) BOOM BOOM BOOM they explode when they touch either other causing mayhem and death, that would have been a much better way (spoiler if you didn't see the first six minutes) to rob a bank. Or at least a more Joker-esque way to do it.
His death is going to create a huge following of this movie especially with the rumor that the role caused his death.
