Saw it Sunday night. Gotta agree, Downey was great as Tony Stark, though I don't recall him being a womanizer in the comic series the way he was portrayed in the screen.
The only bothersome part was the two main bad guys (the lead terrorist and Obidiah Swain (Jeff Bridges' character)) were the only sly guys in the movie. I walk out of the flick totally offended.

j/k Awesome movie.
