Dr. Strange in the Multiverse of Madness (MoM) is not Dr. Strange 2. It's not a follow-on from Spider-Man: No Way Home. It is, in fact, WandaVision season 2, and that show (or a good summary) is required before watching MoM. MoM is a feast for the eyes; a rich spectacle with fantastic set-pieces. Some of the fight scenes are particularly inventive and fascinating. And...that's about it. The movie doesn't go anywhere or do anything. The central narrative hook is simplistic and, frankly, very silly. (See spoiler review below.)
Lots of people have been saying how good Xochitl Gomez is as America Chavez, but the truth is her character is just a McGuffin, an object the primary characters fight over. There are plenty of superhero cameos, but they're short and pointless. The acting is superb, but they're dealing with a script that is, in essence, non-sensical. I loved the action pieces (especially a fight using musical notes), and the movie is rewatchable for those alone.
MoM is a feast, but one that leaves you feeling empty. Rating: 3 out of 5
