Definitely gotta go with "You want more!?!?"
Too many alternate Batmen as it is. I'm not sold on the concept of the Dark Multiverse even at the baseline. The execution we got though, of a Dark Multiverse largely populated with overly grimdark killer Batmen with different DC characters' super-powers, almost sounds like an overly on-the-nose parody of everything wrong with DC, that got greenlit by accident.
