DC flopped during Marvel's prime era because thew threw away what made DC media unique and tried to copy paste Marvel's style like an ad.

After MCU hit endgame, there really was no plan forward so Disney did what Disney does best and started chuking money at new movie ideas expecting it to rake in the same amount as before.

DC meanwhile did another reboot and ended up back at square one trying to copy any superhero genre film that succeded which led them nowhere.

This genre is effectively dead for the foreseeable future because neither studio tried to experiment with the formula outside of single hits which doesn't bring in enough money to satisfy the corporate overlords at Disney and WB.

They demand an output of several projects a year which is too high for creating something genuinely new.

Rest of Hollywood probably won't greenlight anything because of oversaturation, and the two comic book giants will continue to pump out slop in an a poor effort to maximize profits like they already did with every other franchise.
