Finally caught up with this since its showing on Sky Premier here and TIVO'd it. Watched it over 2 nights as no-one else in the family was interested, so it went on late and after the first couple of hours it was near 3 am and I was too tired to stick it out in one sitting.
The first half I watched up to the moment they decide to resurrect Superman and Cyborg puts up the hologram of him. Thought that would be a good point to pick up from tonight.
So...First 2 hours and change I did think certain scenes dragged out, some felt unnecessary and did find myself wondering where cuts would have had to come had Snyder been able to finish the theatrical cut. But it was still interesting to see just how different it all felt with his hand guiding it as he intended. Steppenwolf's design is much better, Cyborg's backstory should never have been cut and Flash benefited too from having more screen time for his story.
Into the second half tonight I wasn't wondering about possible edits any more and just rolled with it.
Now, I didn't care much for BVS. In fact I watched that again a couple of nights before as a little prep and skipped half of it. But I did enjoy Snyder's cut for Justice League. There were some things I still disliked, but that's always the case for me with Synder's films, however this was better than BVS for me and way way better than the Whedon finished theatrical mess.
While he would have had to cut it down by an hour or so and remove some content to drop the R rating to make it viable for theatrical release, I would say he can feel vindicated and bravo to the fans who helped make it happen.
Now I understand the fans are pushing for Snyder to be able to continue the story, but since he spoiled his plans I would imagine he'd have to do something different now if he was given that chance.
While I will never be a big fan of Snyder, after watching his cut for Justice League I would be interested.
