I can't help to expect a lot of bias phaggot fan boy comments in this thread.
But here is my take on the movie. Obviously action and the epicness you expect from a movie of this magnitude was A plus. Anybody that can't see the dialouge and jokes were very corny and forced is a fukking goofy ass cornball. Some of it was on point but other times it was just bad and if it wasn't avengers you would acknowledge it as cheesy bad writing. I like how they touched on some dark topics but they really just nicked the surface and didn't get in deep. The black widow hulk love story was forced and came out of nowhere. A lot of the movie was rushed and not explained or given enough screen time to add why it's important and possible to the story. Ultron was nowhere near as badass as you thought he was going to be. He was actually too comical IMO. I really want to see one of these movies where the bad ass villain is the guy that gets int he trenches and starts handing that work , a real team buster. Like how many times are we gonna have this internal strife between people on the same team and half the battle scenes are internal and the final scene involves and invasion of fight fodder (aliens, Ultron clones, etc) in a city with everybody going all out. Story feels convoluted at times and a big mish mash of sh1t.
Overall it's not a bad movie its really a slightly above average movie. Honestly I liked it way more than GTOTG and the sad thing is it will have a lower rating than that movie and I will never understand why.
