I was never an Iron Man fan. In fact I used to find the entire Avengers team (Captain America, Thor, Iron Man, Nick Fury, Hawkeye etc.) boring. But this movie exceeded my expectations and has more fun and spunk than it's recent contemporaries like HULK, Spidey3 and Superman Returns. Just go watch it.
Call me a cynic, but walking into Iron Man, I began having these panicky thoughts about ways they could mess this up. Iron Man was one of my favorite superheroes, especially because he was all cool and zero angst among all the superheroes fighting their inner demons, and I was wishing hard director Jon Favreau doesn't fall into the standard origin story trap - too much existential dilemma. Oh, and the recent spate of dark and gritty superheroism (even our boy in blue Superman wasn't spared this treatment) also spelled doom for this character.
