Where is Killing Joker Hiding?

There was an era of comic and superhero cinema where the point of superheroes were supposed to beat the bad guy where the bad guy wasn't given as much back story as I would believe they deserve. Even though The Joker was Batman's opposite since the beginning, he wasn't taken particularly seriously. You could try to argue, "well he's a clown" but that can be argued with two major points 1) clowns are terrifying. 2) None of the characters in the Adam West Batman were taken seriously. But then The Killing Joke came along and the story is terrifying. I won't tell you what the Joker does but it is MESSED UP. But the writer Alan Moore did something really cool with the character. He expanded on it while keeping the core essential elements to who the Joker is: a sadistic clown. If you want to know where you can see the most accurate portrayal of the character is (what a shock) Heath Ledger's Joker. Although they never actually describe him as a clown in the movie, the two parts that express who The Joker is more than anything are 1) the magic trick and 2) when he has the frag grenades in his coat and he says, "lets not blow this out of proportion." I highly suggest you check out both of the Joker pieces I talked about because they're both awesome.
