9 Reasons Why Justice League Is Now Officially The Lowest-Grossing DCEU Film
3. WB Rush
As mentioned, WB made some exceedingly questionable choices in the final stretch of time leading up the film's November release. The two-hour runtime mandate was certainly one of them but so was forcing the film to come out on its scheduled date.
Whedon had just a couple of months to perform reshoots and deliver a final cut that, from most accounts, essentially restructured the entire film, especially the Superman arc. WB could have easily pushed the release back a few months and at least given Whedon a chance to make something out if it, but it is now clear that all they were interested in was meeting a quota.
As was reported a few months after the film's theatrical release, WB higher-ups would not have received their Christmas bonuses if the film had not been released on schedule, and thus they made certain that it was.
In making the director switch and then opting to not give the new director any time to do much of anything, WB showed their true colors and essentially admitted that they couldn't have cared less about the quality of the film itself.
