Functioning as both a sequel to Captain America: The Winter Solider andThe Avengers: Age of Ultron, the film is the most comprehensive Marvel Cinematic Universe chapter to date, and while that put a great deal on the plate of writers Christopher Markus and Stephen McFeely, the movie soars because the challenge is accepted and responded to in brilliant and entertaining fashion. Bringing together tremendous character dynamics; bold structure; an emotional narrative earned after years of story work; and spellbinding, fun action sequences, it’s everything a blockbuster should be.
