>>100209295They put Zack Snyder and David Goyer in charge of the whole thing.
Zack Snyder, who read the tragedy that is Watchmen and the farce that is Dark Knight Returns and thought they were meant to be taken as a serious adventure story instead of warnings to not let capeshit become like that.
And David "she-hulk is a bimbo slut created so the hulk would have someone to fuck" Goyer. David "the only people who have heard of Martian Manhunter are virgins" Goyer.
These are the two people put in charge of the DCEU. You tell me what went wrong.
