Civil War is basically Avengers 2.5 and Marvel throw everything at the film. Interestingly, this film never hit the heights of the previous Avengers film, just odd when you consider everyone involved. The Marvel films at this stage were very connected and started growing towards Infinity Wars. This at the very core is a Captain America film, and a continuation of the first two films. I've never cared for heroes fighting one another, but Captain beating Iron Man is icing on a cake though.
