Acting was solid, but going on about best actors and such is a bit much. I actually enjoyed Iron Man more, and it's not due to DC vs Marvel nonsense either. This was a very long movie, and while I wasn't in a rush to leave I didn't feel that it moved quickly along like most great movies have a tendency to feel. They did a great job with effects and writing. Most action flicks have either one or the other, but not both. I would recommend it as one of the better comic book movies up to this point.
