I enjoyed it. Loved the Cap'n America ending. Liked the Big Thorowski. Had no idea who half the characters were. I'm OK with Dead Tony. More Pepper for me. And they answered the question of why Strange was such a putz, albeit lamely.
The battle sequences are perfectly timed for bathroom and concession breaks.
Did they film 1000 Lee cameos for all the rest of the movies? It would be great if he was still showing up 60 years from now when everybody else is dead.
