I've seen this move twice; once on IMAX and once at a regular screen. The IMAX Experience is definitely better than your standard movie experience. The images of the movie were more detailed than on a regular screen. The sound was completely engrossing and made any slow areas moot. Obviously Heath Ledger's Joker is phenomenal and whenever there is a Joker scene I sat in amazement. I didn't like Christian Bales voice when he donned the mask. But otherwise the film was enjoyable
