Worst: Cut to Pieces

Lastly – and this might be the main reason Justice League didn’t work (or didn’t meet fans’ expectations) – we have to mention the studio’s meddling. This has happened with other movies, so it’s really no surprise.
You may have repressed the memory, but Suicide Squad was a great example of this. David Ayer did dash off the script in just two weeks or so. There were reportedly three final cuts, so is it any wonder that Suicide Squad felt so disjointed?
The same goes for Justice League. As far as we know, Snyder had a vision for the entire shared universe, with Justice League as its crown jewel. However, when the first reports that Batman v Superman was a disaster appeared, it was announced that Justice League would be a standalone movie rather than the announced two-parter.
The fans’ disappointment in Batman v Superman prompted more changes, and Justice League was hailed as a much lighter movie. This resulted in major changes, including to characters such as Batman and Superman.
The disaster grew in scope when Snyder stepped down and Whedon signed on. This is unconfirmed, but we can safely assume that the studio ordered the extensive reshoots that brought on all of the negatives listed here.
Reportedly, Snyder’s Justice League would have been three hours in length. But Warner Bros. decided to squeeze everything into 120 minutes, give or take.
Studio meddling, although they said that the DCEU was director driven? Of course.
