Watched the first 3 hours 20 minutes of the Snyderverse Cut - finish it off tonight.
Started off a bit slow, but it's worth persevering, because you get a lot more back-story for the other characters, with occasional superheroes (appearing briefly) that weren't in the 2017 version (Green Lantern, Martian Manhunter).
Only one small niggle/comment - Avengers:Age of Ultron would like their opening scene back, please...
