A great deal of fun to have all of these characters together in one film. It tries almost TOO hard to give everyone calm moments of dialogue to deepen characters and motivations, but as a whole it works quite well. It's nice to see Scarlett get a good chunk of time, but we get a bit of a short-shrift with Renner's Hawkeye, and nearly the same for Thor I felt. Iron Man, Cap and Loki have great parts, and Banner/Hulk positively steals the show. 3D added some great effect in the final battle. A couple of shockers, one after the main credits, and a fun scene at the end of the rest. Assemble your fanboy friends and go, soon!
