I feel like DC really would be much better off being stripped down to core group of titles that can sustain large volumes of the world and can feed off of each other into crossovers and then everything else that isn’t fully baked should just be a graphic novel.
So like you have the Bat books, the Superman books, Wonder Woman, Green Lantern, Flash, JLA, Aquaman, and maybe Titans. Keep it at like a manageable 25 titles. So if you’re a total DC junkie you can follow the bulk of the universe for 100 bucks a month if you care to and it’s easy to get crossovers over off the ground.
But if some writer has a Booster Gold idea and they can’t heavily pitch it as something that can sustain 10 years and will function well in crossovers and be cohesive with everyone else.... make it a graphic novel that’s special and focused.
