Eh. [spoiler]I didn't like the fact that in the other 2 movies Iron Man was pretty much invulnerable and the suit couldn't get damaged very easily, but in 3 it's like the suits were made of glass. Christ, they were falling apart left and right. Also, there was really no explanation for the bad guys being able to basically turn into lava. I mean, the plant at the beginning exploded when it was torn, but why do humans have the ability to become plasma and breathe fire?[/spoiler]
