For some a divisive movie is a bad movie, while for others it simply doesn't appeal to them, and you can take it or leave it depending upon your personal preferences.
A lot of people seem to view Zack Snyder's Batman V Superman: Dawn of Justice as the former, and would rather see the Justice League handled by a different director, thus the creation of this petition by Bryan Cruz.
It's my disagreement with one point in particular that struck me after reading it, located in the second paragraph. Bryan writes "Even if you loved Man of Steel and BVS. There has to come a time when WB and DC want someone at the helm that can create something that WON'T divide people in such a way. "
Why not? I disagree on the point that a divisive film is a bad one. Not every film has to be to everybody's tastes. I have no problem with Snyder or any director going with a singular vision of a property, and not diluting that formula with things that are included simply to appease a broad audience.
Part of me even thinks that all the back and forth and differing opinions has helped the film pack in theatres for multiple screenings. If you think the film is bad, that is perfectly fine, or if these characters are not the ones you would like to see recreated on screen, that's fine too. I will never berate a film or a director however for dividing people. Some of the best stories in comics have been that way, and some of the worst as well, but that factor alone isn't worth kicking Snyder off the franchise.
