What people have against DCEU ? Maybe part of the reason is because Snyder started it.
Earlier, I used to think that many fans are just anti-DC (well, some are..) but now I think that they can't stand DCEU because Snyder was the Architect of phase-1.
That and some fans are totally against the actors Snyder has cast in DCEU (namely Eisenberg as Lex, Leto as Joker, Ezra as Flash, Gadot as WW, Affleck as Bats) smh. And, DCEU's poor performance with critics isn't helping DCEU at all.
Some people are still not onboard the DCEU, even though Snyder is no longer involved in DC movies. I'm beginning to realize having much 'acceptable' casting choices would have made things easier.
As much as I love Ben Affleck and Gal Gadot in their respective roles, DC would have been much better off had they cast fan-choices like
Anson Mount/Josh Brolin for Batman, and
Elodie Yung/Olivia Munn for Wonder Woman and
Bryan Cranston/ Timothy Olyphant for Lex Luthor.
