I liked it - I'd give it a slight edge on #2, but not much. I did roll my eyes when Stark started dancing - totally reminded me of Spider Man 3 and 'dark' Tobery Maguire... any thing that reminds me of that film is a little heinous.
I was disappointed in the Mandarin character. I wasn't expecting the whole puppet thing, though it made sense with the introduction of AIM (where were the beekeeper suits??) and needing a front to do their thing.
I laughed at the after credits scene, though my wife forgot who the Dr. was so she didn't get the humour right away.
