5. 'Captain America: Civil War'
It's probably way too early to say such a thing, but it's possible that we've reached peak comic book movie. That may sound crazy considering the fact that Captain America: Civil War grossed $1.15 billion, but that's significantly less than Iron Man 3 and both Avengers movies. It's ostensibly a Captain America film, but nearly all of the important Avengers (with the exception of the Hulk) appear in it. It's about a rift that occurs within the Avengers when there's a UN proposal to oversee their actions. Iron Man thinks that's a fine idea, but Captain America does not. Lines are drawn. There are fights. The stage is set for yet another sequel.
