After rewatching Civil War multiple times, (not necessarily legally) I have come to the conclusion not only is this the best comicbook movie ever, its an expertly crafted move. Not just because it expertly juggles so many characters and has so many quotable lines but also there are so many themes that are explored among all the punching and size changing.
First off Zemo. The promotion of the movie was that both sides are right and here we have a 'villain' who is actually right. One could even argue Zemo is the protagonist. This is a movie about his plan for revenge. Zemo is the voice of innocent bystanders given form. He is the tactical genius smart enough to decrypt the Hydra files and realise that there might be skeletons in the Avengers' closet that he could use. Best of all, the twist has been implied in Winter Soldier.
Speaking of revenge, we've got two other characters seeking revenge as well. Black Panther who ultimately comes to different terms with his need for vengeance (thank the Marvel gods that he stopped Zemo cause Zemo is the best villain since Loki) and Stark who is just I don't care Winter Soldier was mind controlled because everything in my life has fallen apart and revenge is the only thing that can make me feel better.
Civil War is great because it pays off the character development from previous movies. The soldier who was used to chain of command who comes to realise that all organisations are easily corruptible and the safest hands are in his. The rebel who has made so many mistakes who realises that he can't keep running away from accountability.
The scary thing is how can Marvel movies get any better? Can the peak get any higher?
