The funniest and most tragic part about all of this is that Warner Bros/DC created the "MCU" model in animation over a decade ago.
Batman: The Animated Series, Superman: The Animated Series, and then Justice League & Justice League: Unlimited. The creative team understood that they had created the base by giving us two entire shows that fleshed out these two great characters over a series of years to allow that as "build up" to Justice League to create a "shared" universe.
They were ahead of their time and Marvel Studios/Paramount at the time took advantage of that model and now Disney has pumped it with HGH and TEST and has made MARVEL into the leading brand in the superhero genre.
That's how you create a world. I was willing to give this endeavor a chance with some major reservations that I and herolee and many others kept talking about. With that said I love BvS but my business/sustainability part of me knows this isn't good for the DC film brand at all.
