Dr. Strange and a couple different universes of mild inconvenience.
Multiverse this is not. We get a 30 second montage of a trip through realities in a multiverse, but mainly we stay within 2 similar universes.
The main villain being a friend who just wants to be a mommy is pretty lame.
Probably would have been better had Wanda not been bad and just joined Strange and America Chavez in figuring out how to control her powers in the Multiverse.
A fun adventure with bad stuff along the way.
We don't need more stories with Avengers turning bad. It's getting boring.
