The only reason people still watch Marvel movies is inertia. If you dropped some of them as stand alone with no prep whatsoever like Ms Marvel, The Marvels, etc., the numbers would be horrible. The Disney+ shows without the movies...horrible. Sure, the movies lead into the shows as part of a multiverse or whatever, but your pre-Endgame movies could generally stand on their own. The new crop is not in the same situation. They suck and they only reason people watch them is brand/ loyalty inertia, thinking the next movie or series is the "next big thing." Problem is, there is no next big thing.
The Marvel franchise might continue to make money, but it is otherwise dead. Even then, the money is from people clinging to a 10-20 year old dream. People hoping for a cameo or whatever. Hell, people are hyped about alligator Loki, like...come the fuck on, people. You might as well try to solve an Amber Alert by surveilling the local day care from a blacked-out '86 Ford Econoline van with "free candy" painted on the side.
