I'd love to see the Snyder Cut. Regardless of whether it ends up being better or worse than the theatrical version, it would be a fascinating exercise in comparing two visions of a movie that had impossible levels of studio expectation on its shoulders. The only downside is that a true return to the original plotline would give us Justice League Part 1, the first half of a duology that would never be completed.
Despite the building media momentum, and interest from the original cast and crew, it all counts for nothing without studio backing. I'll be very surprised if it actually happens.
