|So Much Stuff!
There is a TON going on. So much stuff it's hard to describe. Basically the story is about the world's first fully intelligent artificial being, Ultron, and his attack on the world. The Avengers, being the Avengers, have to stop him. Honestly though, that's not what the movie is about. This is a Joss Whedon movie, so it's about character character character.
One of the high points of this movie is that it gives us a nice look at Hawkeye's character. He doesn't have his own movie so giving him a lot of screen time here is a good choice. You also get some unlikely flirty stuff going on with some of the characters as well, that was fun to see. Probably the best sequence in the movie is the all character and no action party scene where everyone, including Falcon, Warmachine and several Shield agents are standing around chatting it up.
And The Vision! He's fantastic. Quite the addition to the movie franchise.
I'd recommend this movie to just about everyone, it has some comic violence so if you aren't into that then steer clear. It is essential viewing for anyone that liked the first Avengers and any comic book movie fan. Comic book fans will probably also like it but maybe not quite as much, Ultron is certainly not as scary as he is in the comics.
I try not to criticize anything here, my goal is to keep it all positive, but I will warn you on this one. This movie has a TON of moving parts. Too many I think, so be prepared, if you are paying close attention you might get exhausted. I advise you to switch off and just have fun. This one is a real roller coaster.
