Saw Iron Man 2 tonight. Interesting. Not as good as the original, IMHO, but still enjoyable. As always, Downey stole the show. The fight scenes were pretty weak, IMHO. They didn't last all that long, and weren't all that spectacular. That said, the dialogue was the best part of the movie. Downey and the Senator (played by Gary Shandling) have a great confrontation, and I have to admit, it's the first time I've heard the word 'assclowns' used in a major motion picture. I was rather saddened by the limited amount of screen time that Mickey Rourke got to share with Downey, but what was there was good.
And there IS an easter egg at the end of the credits. You can decide for yourself if it's worth the wait.
