this is supposed to be a political thriller like The Winter Soldier and Civil War. Each explored a theme with geopolitical ramifications, fueling the story. The Adamantium plotline is that theme, but it serves only as a backdrop to the main story of Sam trying to prove himself as Captain America, which many have argued online that he has not.
Compounding Brave New World’s shallowness is its mishandling of even the superhero elements. A superhero film works because each hero and villain has a defined set of powers, giving the hero advantages and significant limitations. I’m not exactly sure what Sam’s powers are. Obviously, he can fly. His suit is lined with Vibranium, which makes him invincible.
The problem with Brave New World falls squarely on the writing and the story. Any goodwill you feel about this film is all the flashy action sequences and Sam triumphing in the end. In the end, superhero films are more about sympathizing with the hero versus being inspired by the hero and wanting to be a better person as a result. Captain America: Brave New World pales compared to all of its predecessors.
