Steven Spielberg thinks that superhero movies will go the way of the Western. As in, moviegoers will get tired of them and stop watching them and the movie studios will stop making them. That sounds hard to believe since slapping Marvel on anything basically guarantees a gazillion dollars but how long can this current Marvel Cinematic Universe of shared worlds over multiple movies feasibly go on for? When will it end? Can it really go on forever?

ScreenRant explores what could possibly maybe stop Marvel’s current world domination: box office failure, critical failures, unknown weird characters, too many characters, and audience fatigue. I wouldn’t bet on any of those stopping these shared universe superhero blockbusters for a long, long time.
