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.
I thought it was cute, and can be a show worth watching if they stick with it a little while. My favorite funny moment was when the girlfriend got up from the table to go to the bathroom, and the family sees on the TV that she's a serial killer.
