One of the greatest feats of “Spider-Man: No Way Home,” a movie that really does walk a highwire act in terms of cramming multiple characters from various strains of the franchise into a single cohesive narrative, is its third act. This is when all of the characters (heroes, villains, new and old alike) come together for a final showdown. Every character gets their moment and every set-up is paid off. Few modern blockbusters are this satisfying, and the triumphant third act is a big part of it. (This would also go a long way in explaining its impressive box-office tally.)
