Effectively the film is about four characters; Captain America (Steve Rogers), Ironman (Tony Stark), Winter Soldier (Bucky Barnes), and Black Panther (T’Challa), driven by a misunderstanding, a Hydra experiment, the fear of power and differing views of safeguarding the world. The lead up to Civil War with the previous MCU films sets the stage for the fracture between Ironman and Captain America and why after being united for so long they are divided in their views of how their powers should be used. Not just an action blockbuster that satisfies with memorable fight sequences, Civil War raises the emotional stakes and compels the viewer with its treatment of the multiple characters featuring in the film. A definite worthwhile watch.
