So I watched this movie last night, been thinking about it a little bit and there is just one big problem with it that I couldn't quite come to terms with.
So the whole "civil war" aspect of the movie was because they had differences in signing that document that gave the United Nations control over them. During the movie they talk about how many innocent lives were lost during their saving of the world. Does the Secretary of State not see how lives were also saved during all of that? They were essentially saving the world each time, if they hadn't intervened the entire planet could have been destroyed? How are they being punished for that? I really couldn't wrap my head around why they would even consider arresting the Avengers over that type of thing.
Other than that the movie was pretty good.
