Ah, it's supposed to be a trilogy? I thought they're still gonna make an Iron Man 4, and possibly more as time goes on. I thought it was a pretty satisfying superhero movie. It gives you what you want to see in a superhero movie: amazing action, powerful villains, sweet visuals, humor, epic action sequences, etc. I'd say I liked it a lot more than the second one, and just as much as the first.
Anyway, I'm looking forward to reading your review.
