In the grand scheme of superhero movies, 2018’s “Spider-man: Into the Spider-verse” swings the highest. It’s one of those flawless films whose casual brilliance belies dozens of open-hearted, risk-taking decisions we’ll never know about, but that translate fully to the screen. In telling the jaw-droppingly animated story of Brooklyn teen Miles Morales and his self-realization as the alternate-universe Spider-Man (on what’s known in Marvel as Earth 1610), it also centered Black and brown lives in its narratives, music, and eclectic, hand-drawn art style.
