Never liked the character, just like I don't care for Robin. I prefer Joker and Batman to be loners, the flip side of each other, the "you complete me" thing done so brilliantly in TDK.
But of course, to each their own
Also in terms of the look of the Joker,I think they should go back to the source. My avatar partly inspired the creation of the character, maybe they should do something closer to that visually. I want him to be skinny and scary like in TKJ.
