good movie, but no where near as good as the first one.
Ultron is one of the best villains ever, and he was not developed into his powerful self at all....
Bruce Banner/Hulk pissed me off all movie because his story was fucked up in this movie and basically non-existant (Same w/ Black Widow)
Hawkeye was amazing, but it would've been so much better if he had his own movie prior to this avengers, because they just all assumed that everyone knew Hawkeyes backstory coming into this movie (even tho he only had like 10 min of screen time in the last avengers movie)
Quicksilver and Scarlet Witch were WAY too underdeveloped for this movie...they play such a bigger role than they actually did in this film.
other than that, it was still enjoyable and the action scenes were great haha
