This is a movie that feels large even before it hits the IMAX big screen. The Dark Knight grabs you and doesn't let go for the whole 2+ hrs. Heath Ledger's Joker lives up to the hype and may drive me to see it again just to watch him one more time. But... As good as this movie was, I didn't walk out saying "Wow that was a rockin' good time!" like I did with Iron Man. I think Favreau did better with the performance he got out of Robert Downey Jr. and connecting with the audience. Christian Bale's grunting dialog with the suit on became annoying. Really, you don't need to disguise your voice Bruce. Iron Man was better because it had all the good things DK did AND it was fun. Still.... go see Dark Knight! On IMAX!!
