I liked it a lot better than the mixed reviews I was reading would have led me to believe. It's not as fresh as the original, but the charisma and humor were there, and so were some great surprises. RDJ was amazing as always - it's hilarious that Iron Man is a funnier superhero than Spiderman, but the improv makes it work. Thumbs up! I think that anyone who enjoyed the first movie will like this as well, and enjoy a great thrill ride! And don't forget to stay after the credits for yet another Marvel movie tie-in that leads towards the inevitable Avengers movie in 2012! Don Cheadle did a good job - ScarJo was good, but not what I imagined the Black Widow to be like, but she *was* hot... And Gwyneth did her usual impeccable job. Mickey Rourke added weight to what could have been a cardboard cutout stereotype, and Sam Rockwell's character, though annoying, was well played.
