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.
So all the kids can watch SHIELD, and the adults and grandparents can watch NCIS? Seems straight-forward. I think I'm more interested in ABC's new offerings than those of any other networks. SHIELD is a given, as I believe in the Shield.
