'Man, Justice League really was awful'.
Fixed it for ya.
And people really want another cut of this terrible movie.
Complete nutters.
I had the experience of noting a big difference in quality from BvS theatrical release to the Ultimate Edition. WB butchered the theatrical into a nonsensical mess.
So, like it or not, the studio themselves developed this paradigm of audiences expecting to see the better movie... that existed before they made it "commercially viable."
This is practically a WB/DC tradition by now. Plenty of stories going around about Burton's third Batman with a Billie D.Williams Two Face before those movies got Schumachered; or Superman 3 featuring Brainiac as the big baddie before producers Golan and Globus made it into a supercomputer designed by Richard Pryor on a cocktail napkin.
The conflict over these movies has always been about PG-13, happy meal toys, non-realistic violence, and marketability.
MCU hit a very nice, delicate, and vigorously defended balance there. DCEU was on its way to a more serious, realistic, and adult alternative... until they abruptly shifted gears into a pale and inferior MCU imitation with theatrical Justice League.
For a lot of reasonable people, there is the expectation there was something better there before studio interference, even just based on past experience. Sadly, the movie we really wanted got arrested at the script phase. Any new cut realized will still be a Frankenstein of R-rated vision and PG-13 compromise.
...but it would be a better one of those than the one we got.
