‘Joker: Folie à Deux’ to Lose $150 Million to $200 Million in Theatrical Run After Bombing at Box Office

Because these kinds of movies have become blatent cash grabs. The market is oversaturated with the same formulistic plots reskinned with a different superhero. It's insulting to consumers to assume high profile actors, flashy cgi, and a comic book character is enough to overlook poor storytelling.
This seems way off base, too, as from my recollection, it was successful because it was the polar opposite of the typical DC or Marvel movie. It was super dark, wasn't full of CGI portals, and didn't have Mary Sue characters that were always perfect.
People were already tired of Marvel-esque superhero movies by this point. It was the same year Endgame came out, which was AFAIK, the last successful Marvel movie and the culmination of an 11 year story. Without that, it probably wouldn't have done so well as even the actors were tired of their characters.
I ask myself sometimes if the movie was not called Joker but "The Clown" would it have done so well.
