The bigger issue is if James Gunn will present a toothless version of Superman to appease the general public.
We've seen that happen again and again. People hated the Jim Carrey Grinch movie, the Johnny Depp Wonka movie, the Bill Murray Garfield movies. They loved the Boris Karloff Grinch, the Gene Wilder Wonka, and the Lorenzo Music, they got offended that the creators would try to do something risky and different them. Then what happened? The studios gave in and delivered toothless, edgeless features like the Benedict Cumberbatch Grinch, the Timothee Chalamet Wonka, and the Chris Pratt Garfield. Inoffensive, without style or creativity or risks, and people accepted them because they don't like anything new. They were very similar to the versions they grew up with.
My fear is that Gunn will try to emulate the Reeve Superman and not try to do something risky like Snyder did for Cavill's Superman.
