Just got back from watching it. Pretty awesome, the hero movie to beat and will stay as the best one for a long time. Some scenes might see slow paced but the dialogue makes up for it. Stark is still Stark but you gotta love the Hulk in this movie.
It deserves another viewing so I'll probably watch it again on Friday.
Stay after the credits, someone
(hint: Infinity Gauntlet) makes an appearance, perhaps teasing us for a sequel.
