Things I know I wanna see in the Snyder Cut
10- More of Victor Stone/Cyborg's backstory and character development
9- The Seventh Member...Originally, marketing material for Justice League included the phrase, "Unite the Seven", but only six members were ever seen on screen when the film debuted; Wonder Woman, Batman, Super Man, The Flash, Aquaman, and Cyborg. Fans speculate that the seventh member could make their appearance in The Snyder Cut, possibly turning out to be Martian Manhunter, Shazam, Atom, or Green Lantern. Snyder's original script had over 10 additional superhero characters in the film, so it could be a variety of people.
8- More context on the time travel aspect especially when it comes to Knightmare in BVS
7- More buddy/buddy interaction between Clark and Bruce
6- Higher stakes
5- Sure as hell no Cavill editing on his moustache...give him that Mission Impossible Fallout mustache or give him a beard
4- More consistent Batman
3- The League fighting as a team...united and together
2- More of Joe Manganiello/Deathstroke
1- Tease Darkseid...build up towards Darkseid especially if he is supposed to be your Universal big bad much like Thanos was for the MCU...Darkseid should be that in this Snyder Cut and then you set the tone for the future of the DCEU going forward
