how are you defining "traditional mainstream releases" and how are comic book movies pushing them AND indie films out of theaters?

besides, "comic book movies" is a misnomer when that can be anything from Scott Pilgrim to Ghost World and you're clearly talking about movies based on mainstream superhero comics that are made by four- now three studios (Marvel Studios, Warner Bros, Sony and formally Fox)

I could see if people were bitching about Disney in general buying up so many studios and jerking theaters around and which films they can screen; they'd have a point, then.

But Marvel Studios releasing three films a year isn't stopping a filmmaker like Jordan Peele from making very successful original films. The Avengers aren't pushing anyone else out of theaters. Everybody eats, b.
