I thought the aesthetic was to help keep the universe looking more surreal like a comic book. I think it helps from keeping the more flamboyant elements from looking so jarring. I know you're much more knowledgeable about comics than me, but wasn't it similar to them making everyone in colorful green, purple, and orange outfits back in the day to give less of a contrast between heroes? Maybe after Justice League forms they'll start brightening things up. I think it could be a neat artistic direction. I understand the complaints against Snyder, but I think it's great that he's not apologetic for the material. While I might not be a fan how certain things are executed, I appreciate he has so much passion for superheroes. He's not like Tim Burton who said that he'd never even read a comic book (Although, I believe he read and enjoyed The Killing Joke.) Snyder makes multiple commentaries on the discs, and while I have a cognitive dissonance from what he describes and what's actually happening on screen, he clearly loves this. Thankfully, there's a lot of movies coming out of this from various directors for those that don't like his films. And if they don't like those, Marvel is doing a pretty good job!
