Interesting choice of pejorative there, bro.WB execs are fucking retards, they forget this movie exist, a dark comic movie can exist and do well, only if it's made well, they are trying to copy Disney/Marvel and it's a fucking failure, we don't need Marvel tone, DC has always been darker, get better people to work on your projects, not rejects who decided to build a universe based on a shitty superman movie..
As for this sentence -- based on what? Where does this notion come from? I've heard it several times from people who defended the tripe WB has been putting out. Watch Young Justice, Teen Titans (OG), Batman TAS, Superman TAS, JL, JLU or just read the actual comics. The DC universe is not one devoid of humor or lightheartedness. The aforementioned managed to balance a more straightforward serious approach while acknowledging the inherent silly nature of the medium.
There is more to DC than Frank Miller and 90s Dark Age comics. DC's bread and butter has always been hope and optimism. Hence them returning to with the whole Rebirth relaunch.
