Words cannot adequately describe the sheer and horrific levels of fail and suck contained herein.
This should have ended in one of 2 ways.
The first is for the first time in their lives, the Amazons take their lives into their own hands and side with Diana and tell the gods who have just massively fucked them over to just GTFO, or at least for a bunch of them to side with Diana and in so doing finally choose their own destiny.
The other would be for Diana, as an invariable cosmic level consequence of being a mortal who slays a god, a consequence even the other gods are unaware of, becoming quite against her will, the new God of War.
