Fun stuff! Really cool to see super-powered beings really pushed to their limits. Yeah, they're super-powered and have amazing abilities, but here you really see them sweat and strain to keep up with the challenges that are being tossed at them. One of the things I recognized from the comics when I watched the first Fantastic Four, the item that just rang absolutely true, was the bickering and arguing. Same is true in The Avengers, they're not all happy, loyal, obedient warriors, they're individuals who let each other know when they disagree, but when the chips are down and their backs are to the wall, they pull together and they all act in concert.
