IMAX format was fine--our seats vibrated! As for the movie--ehh! Gyllenhall was miscast--she was not attractive or alluring enought to be the apex of the love triangle. Too many characters stuffed in a very thin storyline. I did not buy the basic premise that good and evil are two sides of the same coin. Bale's screentime was disappointingly thin, and his acting not nearly as strong as in Batman Begins. This is partially due to Heath Ledger's job as the Joker--AWESOME! He created the most villainous monster of a human being since Hannibal Lecter. Considering the rave reviews & boffo box-office, this film was very disappointing. The fact that Ledger is dead gave his character a poignancy that the filmmakers could never have intended.
