Captain America: Civil War is a 2016 superhero film based on the Marvel Comics character Captain America, produced by Marvel Studios and directed by Anthony and Joe Russo. The film features an ensemble cast, including Chris Evans as Captain America, Robert Downey Jr. As Iron Man, and Scarlett Johansson as Black Widow.

The movie received positive reviews from both critics and audiences, praising its action sequences, performances, and themes of friendship, loyalty, and responsibility. However, some fans of the Captain America comics expressed disappointment that the movie did not follow the source material faithfully, especially the iconic storyline of the same name.

The Civil War comic book series, written by Mark Millar and illustrated by Steve McNiven, was a massive crossover event that involved almost every major superhero in the Marvel Universe. The story revolved around the Superhuman Registration Act, a government policy that required all superheroes to register with the authorities and reveal their secret identities. Captain America and Iron Man had opposing views on the law, leading to a massive conflict between the Avengers and their allies.

While the movie borrowed some elements from the comic book series, it deviated from the source material in significant ways, such as the absence of many key characters, the simplified political context, and the different resolution of the conflict. Some fans felt that the movie missed the complex themes and character development of the comic book series, and that it was more of an Avengers movie than a Captain America sequel.

Overall, while Captain America: Civil War is a well-made and entertaining movie, it may not satisfy die-hard fans of the Captain America comics or those who were expecting a faithful adaptation of the Civil War storyline.

However, as a standalone superhero movie, it delivers on its promises of action, drama, and spectacle, and sets the stage for future Marvel Cinematic Universe movies.
