The chaotic "Ant-Man and the Wasp: Quantumania" features both the best performance in the history of the Marvel Cinematic Universe and perhaps the worst.
First, the good stuff: Jonathan Majors. He plays Kang the Conqueror and he is so quietly charismatic that, no matter how many civilizations Kang destroys, you kinda want him to win. We meet him in a prologue, set in a quantum realm. He befriends trailblazing scientist Janet Van Dyne (Michelle Pfeiffer) whose family rescued her in the last "Ant-Man" (the Wasp is her daughter). In "Quantumania," everyone heads back to the quantum world in order to prevent Kang from escaping and taking over the universe.
Majors has been lurking on the edge of stardom for several years, giving subtle, intelligent performances in movies nobody saw ("Devotion," "The Last Black Man in San Francisco"), popular movies that weren't about his character ("The Harder They Fall") and a TV series that should have used him better ("Lovecraft Country"). "Ant-Man" is his first blockbuster, so it's making him famous just in time to gather attention for an upcoming project that wowed them at last month's Sundance Film Festival: "Magazine Dreams," in which he plays a bodybuilder — a physique you can tell he was working toward in "Ant-Man."
