It does not matter how many successful hits you had in the past. Star Wars was historically the largest franchise in history and the Force Awakens made more domestically than any Marvel movie, but Star Wars is now universally believed to be a dead franchise. It looks like the same thing is happening to the MCU, except worse, because Star Wars was not getting megaflops like the MCU is now.
DC did the right thing back in 2022 and frankly, they are now years ahead of Marvel at this point. James Gun's Superman film releases the same year as Cap 4, a film that is a sequel to a forgotten Disney+ show from 2021 and is being reshot again from the beginning...I don't know if Gunn's new DC universe will be successful, but I know Cap 4 won't be.
