One thing with the new Superman movies compared to all the other comic films is they've all been life suckingly long.
X-Men and Deadpool are under two hours. Superman II, X2, XDOFP, Iron Man, Winter Soldier, Spider-Man and Spider-Man 2 are all under 2:15. Some are just a hair over two hours. Same with Batman and Batman Returns. Guardians of the Galaxy. Actually, everything MCU except the Avengers films and Iron Man 3 has come in under 2:10. All the Spider-Man's after 2 have been 2:20+.
MoS is 2:25, BvS is 2:30, Returns is 2:35. All need 20 minutes or more cut out of them. At least that's still less than TDKR which needs 45+ minutes cut out of its 2:45.
I hope Suicide Squad isn't longer than two hours.
I think this is part of the supposed animated DC paradox. They trim some of those a bit too much down.
