Just got back in from seeing Iron Man. It did NOT suck! Robert Downey Jr. was great. The suit was pretty wicked, and there were plenty of things blowing up. Usually I'm skeptical about these types of movies, but they didn't screw this one up.
I recommend it. It's a very good start to the beginning of the summer blockbuster season.
I'd give it two thumbs up but I have one hand down my pants. So one thumb up it is.
