I'm Hoping Aquaman is a huge hit or a colossal Flop.

Aquaman failing would hurt Shazam which is done filming and Wonder Woman 2 which is filming. But they're not just going to junk those two if that happens. And all three are supposed to be mostly standalone like or even more than Wonder Woman 1. There's no Justice League 2 announced anymore so they have nothing to build up to, just lick their wounds and hang in there.
