Warner Bros. and DC just shot themselves in the foot.
I don't know how much the rest of you know about comic book film culture (I'm an expert), but origin stories and recasts are huge parts of it. It's not like it is at Marvel where you can become successful by quipping 100 times an hour. If you screw someone over at Warner Bros, you bring losses to yourself, and the only way to get rid of that loss is by firing Snyder.
What this means is the comic book film audience, after hearing about this, is not going to want to watch Wonder Woman, Aquaman or Flash, nor will they purchase any of Warner's extended cuts. This is HUGE. You can laugh all you want, but Warner has alienated an entire market with this move.
Warner, publicly apologize and cancel the Justice League or you can kiss your business goodbye.
