Yeah, I think people are conflating. This is a huge win for the fans of MoS and BvS. This is a continuation of Zack's story, his themes his tones and sensibilities. The fans have already won, it's being released, no matter the outcome of what happens next or what doesn't happen, it doesn't matter, it's irregardless of the fact that he was able to restore to the fans of his work his vision, and potentially final chapter.
The work is set in stone, if you like his stuff this will be a very bittersweet and much appreciated end to WB screwing every side of the camp over, and if you don't like his work well, you were never going to like this and honestly, I'm sure the fans don't give a ****. I'm happy we're getting something to rectify the misstep that was JL, all the haters have been hating since MoS so their opinions are irrelevant for the simple fact of the matter... this release is a culmination and total sum of Snyder finishing his work for the fans, AT+T provided the money to put to bed the complaints and ill will and give finally what the fans of his storytelling wanted, his vision and almost complete chapter. A complete win, any way that you cut it.
