This. Justice League will be bad laggardly of what cut you release, his cut will be longer and probably worse, but just cut out everything with Darkseid.
Ava is actually a fan of the New Gods and probably knew what they were before 2014, I can't say the same for Snyder. Just look at all 3 of the designs he planned for Steppenwolf. Steppenwolf isn't a complicated character, he's a dude with a horned helmet and a staff and Snyder wanted him to be some sort of demon alien monster, which just screws with the continutiy of the New Gods consider he's Darkseid's uncle and, in turn is the granduncle for Orion.
