I was able to enjoy it as a stand-alone movie. I know a lot of people are saying "What about the other Avengers? What about Shield?" I thought about it, but it didn't bother me that much. I wanted to see how Tony was going to use his wits to handle this seemingly unbeatable bad guy.
I think this will be a problem for all future Marvel movies. The Avengers set the bar sooo high, that expectations are crazy.
This just hit me too, last year people hated how she could be such a dreamer and now...well she realized it too. She's stuck in hell having to pretend she is still happy. Very well written and very well acted both this and last season.
