Wesley Snipe's character in Mo Better Blues said it best:

"That's right, the people don't come because you grandiose motherfuckers don't play shit that they like. If you played the shit that they like, then people would come, simple as that."

IT, Once Upon a Time in Hollywood, Hobbs and Shaw...all non-comic book movies that were box office hits.

Even if superhero movies didn't exist at all it's not like mainstream audience would be running top speed to go see Roma or The Silence on opening night. Thor Ragnarok did not steal the spotlight from the newest Duplass Brothers movie.

People want to see superhero movies right now. I wonder if back in the day people were bitching the same way about westerns.
