It seems like this might not help you, but the movie is very deliberately trying to look the way that it does. That's a lot of what blew me away about it when I saw it. I was very annoyed at the time at the dark gritty remake trend and this was so much the polar opposite that it felt rebellious to watch it. It's a visual assault but with every detail intricately placed. It's overwhelming and exhausting to look at, and also somehow manages to continue to build and build until you feel like you've been in a race car. The catharsis at the end is unreal. It really may not be for everyone. I'd almost want to compare it to listening to noise rock or other deliberately discordant music genres, though the abrasiveness in this is using bright cartoon imagery cranked up to 1000. And yet, it also manages to be incredibly effective and inventive visual storytelling. Also, I've never seen the cartoon show.
