It was decent. Not my favorite of the Marvel comics but not the worst one either. The setting was interesting, the storyline was pretty decent.
However (Don't read if you are going to see the movie and don't want to know what happens):
I DID love the fact that they incorporated Stark Industries into the whole movie, it tied together a few lose ends in the Iron man movies. I found that awesome, especially since Iron Man is my favorite of these series.
Anyway, if you go to see it STAY until after ALL of the credits have rolled. There is an extra little tidbit right at the end that you don't want to miss!
