Spider-Man: Across the Spider-Verse explodes onto screens this week, building on the foundation of the masterful Spider-Man: Into the Spider-Verse with stunning animation, unforgettable characters, and complex themes. The first note I took after seeing it was “so much movie.” Like the work of a young artist who refuses to be restrained by the borders of the frame, “Across the Spider-Verse” is loaded with incredible imagery and fascinating ideas. It is a smart, thrilling piece of work that reminded me of other great part twos like “The Dark Knight” and “The Empire Strikes Back.” Like those films, it leaves viewers anxiously anticipating the next chapter (which will come in March 2024), and it earns its cliffhangers by grounding them in a story of young people refusing to submit to a concept of what a hero’s arc needs to be.
