It was quiet nice, not AMAZING, but nice. I like the way they realized the Hulk, with a bit of practice they might be able to churn out a decent hulk movie sometime. All in all the best element was Colbie Smulders booty, true story.
Hint, at the end, when caps shield comes up with the credits and what-not, WAIT, a few people left before the very very end scene and it was a zinger.
