From the Russo brothers, who directed the edgy spy thriller Captain America: The Winter Soldier, comes this new Captain America production in the same vein as its most immediate predecessor. There is more territory to cover in Civil War. Two of the original Avengers are missing (i.e., Thor and The Hulk). Hawkeye has more or less retired to his country estate. Tony Stark seems concentrated on funding research, while the two remaining (Natasha Romanoff and Steve Rogers) have, since the events related in Avengers: Age of Ultron, focused their efforts on training the latest crop of Avengers (Vision, a.k.a. Jarvis with a body, Wanda Maximoff, the surviving twin with mental manipulation skills, and Sam Wilson, a.k.a. Falcon).
Thanks to their latest escapade, after which a lot of destruction has been left to clean up by the Wakandans in Nigeria, the Avengers are divided. Tony Stark, Rhodey, Natasha, and Vision are in favor of signing an agreement to regulate the comings and goings of the Avengers by the U.N. Steve Rogers disagrees; in his camp are Wanda and Sam Wilson.
Just when a hundred plus countries meet in Berlin to sign the accord, a bomb goes off killing many of the participants, including the king of the Wakandans. His son, newly minted king, swears vengeance against the author of the massacre who appears to be Bucky Barnes, a.k.a., The Winter Soldier.
Steve Rogers tries, with Sam's help, to reel in Bucky, but he learns that Bucky wasn't the perpetrator. After a complicated chase, Bucky, Rogers, and Sam are detained along with the new king of the Wakandans, who as a Black Panther, had been in Bucky's hot pursuit. Next thing we know, the Avengers will be pitted against each other as planned by a man who has lost everyone because of them.
This is by far my favorite Captain America installment. The humor is understated as the drama that pits them against each other takes center stage. This is an Avengers movie of sorts, since the most recent troop of Avengers plus two more Marvel characters that we have independently come to know (Ant-Man and Spiderman), participate in the showdown. In the spirit that joins them, Natasha asks Hawkeye amidst the fight: “we are still friends, right?”—to which he replies “depends on how hard you hit me.”
