So from what I'm hearing is that we have another disappointing villain character. I really can't think of an Iron Man bad guy that's actually worth noting. Fing Fang Foom? 
It's a good thing that the actual character of Tony Stark is so interesting (and that Robert Downey Jr. does a fantastic job with it), because everything else in the Iron Man universe is just so bland. He really shines as an Avenger though.
Oh, and I've heard that there's a hint at the Thor movie at the end of the credits...
