You're missing the point entirely. Marvel films are oversaturating the box office and pushing out smaller films. Disney monopolizing the industry means smaller repertory theaters struggle to survive, and their harm extends beyond clogging chain theaters with Marvel films on multiple screens.

Disney acquired 20th Century Fox and immediately banned repertory and independent theaters from screening their old films. Anniversary screenings of Alien at the local second-run theater? No more of that. Holiday screenings of Home Alone? Not unless big Disney is doing it through a multiplex.

The people seriously and repetitively condemning Marvel and Disney are doing it because their effect on the industry as a whole is hurting filmmakers who don't or can't work within their globalized, board-approved, algorithmic system.

If you read any of the essays by Martin Scorsese on the subject you will understand that the problem is rooted in this oversaturated, homogenized landscape and that no one is saying these films shouldn't exist, but it isn't as simple as people complaining because they dislike superhero films.

You mention the wide swath of releases of other films, but how am I going to see any of these other films when their release windows have been cut in half so Disney can run another five screens of the current Marvel installment?
