So, it doesn't seem like it would necessarily be a slam dunk to guarantee that a 100% Snyder-directed Justice League would result in an absolutely better movie than the final theatrical cut of the team-up film we saw this past November.
This, of course, doesn't mean that Snyder's own version of Justice League shouldn't be released, it just means that there's no guarantee that once we get it that it will be demonstrably better than what we originally got.
it would have to be an effort that would prove to WB that it would be beneficial and profitable to go through the effort of actually bringing Snyder back to complete the film that he intended to make on day 1 of Justice League's pre-production.
Combining a pandemic with a hungry entertainment industry, the impending launch of a new streaming service, and a relatively modest budget (when not counting the money already spent on the film's theatrical version) have allowed the stars to align for the studio to see this as a profitable endeavor.
This is likely the kind of future effort it would take in order to bring Snyder's original vision for Justice League to life, and since it's happened before, it may not be the best bet to assume that something like this could never happen again.
And now we know that this is pretty much exactly what is happening now, albeit through a far more massive and focused effort than the one undertaken by Donner and Michael Thau in 2006.
On top of this, the conspiracy theorists who contend that original composer Junkie XL has a full, finished alternate Justice League score ready to replace the work of Danny Elfman just simply don't have a leg to stand on.
This is one part that may NOT be true, since it's possible that Junkie XL was replaced by Danny Elfman after completing a substantial amount of work on Justice League.
it doesn't, at least not in any form that would be anything near presentable to the public at this point in time.
Even after today's (5/20/2020) news, this is still true. We're at minimum 7 months away from release, and an estimated $20-30m is needed to actually get the new version of the film in presentable shape before it bows on HBO Max next year.
