Here are some critic blurbs that I wholeheartedly agree with:
Ultimately, it all comes back to Whedon: His clear vision for each character and how they might be profitably intermingled; his unexpected knack for action choreography; his funny, tender, immaculately constructed script.
Mark Ruffalo was born to the play The Hulk. There is a ten second epic action sequence that is worth the entire price of admission and every one of your nerd tears! Hulk Smash!
Whedon can deconstruct the myth of heroism in his sleep, and probably does, but on this occasion he’s here to redeem the cliches, not to bury them.
So let me just save you some time and say this movie will break your hand with its cock and balls by running at your hand which you’ve made into a fist, thinking, “I’m gonna punch this movie in its cock and balls ‘cause no fucking way can it be good” but then before you do anything the movie runs at you and breaks your hand with its cock and balls because its cock and balls are like a chunk of highway. They can use this part of the review on the poster.
