Let me start with the fact that I am NOT a Heath Ledger fan, and I AM a Jack Nicholson fan. That being said, Heath out Jokers Jack by a country mile... His portrayal of the Joker is legendary... menacing, disturbing... all the things he should be. He makes tha movie very plausible, save a few of the technological gadgets. The movies only flaw is the fact that Maggie Gyllenhall does not possess the physical beauty to make 2 billionaire model type men chase her, but aside from that, the plot was great, and the action was better, the direction was great and the acting superb, especially Ledger. MUST SEE from me and I say to go the Imax to see it, you don't want to miss a morsel...
