Captain America: Civil War begins the next wave of Marvel movies with an action-packed superhero blockbuster boasting a decidedly non-cartoonish plot and the courage to explore thought-provoking themes.

Thor is imprisoned on the other side of the universe and finds himself in a race against time to get back to Asgard to stop Ragnarok, the destruction of his homeworld and the end of Asgardian civilization, at the hands of an all-powerful new threat, the ruthless Hela.
