JL and BVS were intended to be for DC what the Avengers is for the MCU, making sure the unknown characters add value to the whole universe and that translates to fans having to watch those movies in order to follow the next episode of the chapter. But JL and BVS not only destroyed their own reputation, but are also hurting any chance the other movies in this shared universe have of perform well in the box office.
It's kind of defeating what it was meant to do.
