Call me old fashioned, but I still enjoy a movie that develops the characters and builds steadily toward the inevitable big action showdown. Jon Favreau is well past proving himself as a director, and yet he takes it to the system once again by refusing to stick to the formula note for note. The pace of the film, while noticeably slow at times, works to avoid the eye-candy fatigue that happens when you see too much cool stuff in a row. Instead, Iron Man gives you a little bit of amazing at a time during the first two acts, leaving you anxious for the spectacular finish. Likewise, the viewer is invited to chew on the more subtle, complex character relationships, with excellent performances from all. This isn't to say the journey is boring. while I loved the big finish, I got just as much of a kick (maybe more) from watching Tony Stark design and test the suit, while exploring his new perspective on life. My only criticism was in the story structure itself. At times if felt as if some pieces had been wedged in from a different puzzle, at other times I sensed an intrusion by lowest-denominator sensibilities. Perhaps this is an unavoidable side effect of working with a long established franchise. All in all, I hope Iron Man's success will inform other action directors' decisions, and will convince them they need not be afraid to let ten minutes pass without an explosion.
