I know that we are being told that this is the greatest movie since God walked the planet. Not to take anything from Heath Ledger's performance, which IS above par, there were too many loose ends. I expect that Ledger's death resulted in a significant amount of angst in completion of the film. But what happened to the Joker? We are never told. And why do Batman producers find the need to slip in more than one super villain? The movie would have been just as good (if not better in my opinion), if it had remained focused on the Joker.
