I’ll say what I said in another thread: while there hasn’t been all that much Multiverse stuff, it feels like more because three big sequels did a Multiverse related story. Spider-Man 3 at least kept its story specific to the franchise, but Doctor Strange 2 and Ant-Man 3 did stories that were a big departure from what they’d done before, and if you didn’t like one or both of those movies, it felt like a franchise getting hijacked by the Multiverse/Kang storyline.
Ironically they thought (according to the recent Hollywood Reporter article) they were doing the Ant-Man series a favor by making it “important” enough to set up the upcoming Avengers movies.
Which is another current problem with the MCU; if they thought Ant-Man 3 was going to be a hit then they don’t understand the audience as well as they used to.
