There hasn't been a superhero movie of this caliber since the first Spider-man! Robert Downey Jr. IS Tony Stark, and no other actor could have portrayed Iron Man better than him. The movie moved so seamlessly, I didn't even realize it was 2 hours long! I've seen this movie TWICE in the past 24 hours, it's THAT good.
If you've been waiting for something worth paying those high ticket prices, do yourself a favor and see this movie. You won't be dissapointed!
