No final hulk-out!
I think this was a mistake, though I enjoyed the overall film-- they should have had a final hulk out in the climax-- when Banner escorts the woman to safety from Fisk Tower, he should run back in to try and help Matt, but gets rousted by some Thugs, then turns into the Hulk and starts wrecking stuff, and helping Daredevil..
