Besides the needless murders, the Joker just seems like someone you would champion.
Well, the Joker is kinda cool I guess, but then again he is a complete wacko, so....I cant say I love him.
As for everything else, Heath Ledger (Joker), had an excellent performance, and he really was the perfect guy for the job. Same goes for Aaron Eckhart (twoface) and Christian Bale (Batman). But really Heath Ledger was awesome, and totally deserved that Oscar.
But as a char, I cant say I love the Joker. I like Batman more than Joker, so.....yeah.
