Zack Snyder cut of The Justice League is what the real DC universe is all about it's dark, gritty Cannon content unlike the Marvels U rated toned down violence, comical style of superhero flicks.
What joss whedon did wrong to Snyders vision was to convert it into Marvel style.
Was it a sabotage by marvel to protect the Avengers or did DC sink its own boat by getting the wrong person for the job.
4 hours of Snyder cut has way better entertainment value than 2 hours of the rough cut off the josstis league.
