The movie started in 1991 where Hydra being brought from a cryogenic chamber, his captors had a book that contains instructions on how to make him obedient to their command. He was then dispatched to steal a briefcase and leave no witnesses. This is later tied to the main storyline of the movie - similar to the Iron Man 3 where the something that happened in the past comes back to haunt us.
As for the what led to the civil war, the destructions and bystanders killed in the earlier movies - Avengers, Captain America 2, Avengers 2 placed pressure on the government to control the Avengers. However, Peggy Carter reminded Captain America that sometimes it is necessary to stand up for what is right even if everybody else disagrees.
The Sokovia Accord was proposed to place the Avengers under the jurisdiction of the United Nations. Tony Stark immediately supported the proposal because of of the guilt he felt after he was confronted by one of the mothers of victims in Sokovia. Steve on the other hand, disagreed because initiatives that were started with the right intend often ends up corrupted by politicians with their own agenda. The confrontation was then triggered by the bombing during the meeting to discuss the Sokovia Accord.
Iron Man’s team recruited Black Panther and Spider Man while Captain America’s team recruited Ant Man and Wanda.
Seem strange that Black Panther was able to hold his own during his fight against the Winter Soldier without his suit and that his suit provides him similar protection as the Iron Man armor. Each of the characters in the movie was almost equally matched with another. I guess this makes the movie more interesting rather than have one vastly stronger than the others.
I cannot not get used to seeing such a young Aunt May. In the comics and earlier movies, she is either much older or had white hair.
The main villain is Captain Zemo, who used to be the Sokovia army. It is impressive how one person could have manipulated the events that caused the civil war.
Throughout the movie, Captain America is reminded that the shield does not belong to him. As in other Marvel movies, this movie was fun to watch with action combined with some humor.
At the end of the movie, Avengers no longer exist as a formal organization, but Steve Rogers left a message to Tony Stark that his team will be available if Avengers is needed again.
The mid credit scene had Barnes (Winter Soldier) agreed to put back into a cryogenic state until a cure is found (for his mind control) in Wakanda. The post credit scene focused on Peter Parker discovering a feature in the web shooter from Tony Stark.
