To be honest, whenever people (even a majority of fans) say “This won’t happen” or “We’ll never get this” history only proves them wrong.
We’re constantly getting unreleased cuts in games, movies and music, some just now media that is even 60 years. So after learning that, I’m going to say “Never say never”.
That said, I’d be okay with an animated version of the Snyder Cut. If we don’t get anything at all I’m okay with that too. I like Justice League and Batman vs Superman so I’m not at all sore about the quality of the already released versions of the films. At least they were a bit better than Nolan’s sepia trilogy who forever gave future director’s permission to butcher villains integrity
