Captain America: Brave New World has adapted many superheroes and supervillains from Marvel Comics into the Marvel Cinematic Universe including Sam Wilson Captain America, Red Hulk, and the Serpent Society. By looking at how well or poorly they've been adapted from the comic book source material into the movies we can learn a lot about what the writers and directors were thinking when they made the movie and see whether adapting these characters and stories well or poorly contribute to it succeeding or failing at the box office. And we can get a sense for how things may look going forwards into the next phase of the CU towards Secret Wars and Doomsday.
