I just watched it yesterday. I liked it. What about you?
I saw it last friday 8 days ago. I really enjoyed the humour and I liked the action as well. Pretty good CG as well and I liked the sounds of the weapons very much, but I was also sitting in an IMAX theatre which makes it even better.
I certainly wouldn't mind if they'd make a 3rd or 4th Iron Man if they stick to the same formula.
