The debut of Zack Snyder'sJustice League is almost here, with HBO Max set to release the filmmaker's uncompromising vision of the DC Universe's greatest team of superheroes. But this wasn't always a sure thing, especially after Joss Whendon's version of Justice League premiered in theaters to disappointing fan response and poor box office results. It took an intense fan response before Warner Bros. decided to work with Snyder on assembling a new version of his movie, which required more reshoots and post-production work. Some people didn't think it would happen, and Snyder is very aware of the voices who were against him.
