Wow. Saw it last night and was really impressed. I think I liked it more than the original Iron Man, which thus far had been far and away my favorite of the Marvel movies. I was expecting a slightly funny, light-hearted action flick. What I got was a really funny action flick with surprising depth and emotion. A couple of minor plot issues, but overall a very, very good movie and one that's definitely worth seeing in the theaters.
Saw it 3D ($14 tickets

) -- compared to other 3d flicks I've seen I think this was a good use. The 3d wasn't overbearing and the movie mostly avoided fast cuts that make 3D difficult to watch.
