The Avengers face their greatest foe yet--government bureaucracy! After another battle on foreign soil has unintended civilian deaths, the U.S. government, in conjunction with the United Nations, is demanding that the Avengers and all other superheroes come under direct supervision of a government committee. The "agreement" is called the Sokovia Accords and the heroes are expected to sign it. Tony Stark/Iron Man is all in favor because he knows the cost in human lives of their actions. Steve Rogers/Captain America is against it because he has seen government agencies fail. As the nations gather to sign the accords, a terrorist attack interrupts. Video footage shows James "Bucky" Barnes/the Winter Soldier was responsible. Among the dead are the King of Wakanda, leaving his son Prince T'Challa in charge and vengeful. He has his own super suit and secret identity--the Black Panther. Steve wants to save his friend Bucky, but that means fighting both Black Panther and Iron Man. Things get further out of control as the movie goes along.
The movie does a good job balancing the serious drama and the action/adventure fun of a summer super-hero movie. The characters' discussions of who should be responsible are interesting and have nuance. The action scenes are exciting and give the chance for every character to shine. The movie also keeps a good sense of humor, lightening the mood.
The movie is a very enjoyable start to the summer blockbuster season!
