I don't know what thread to put this in, but for the reboot's visual style, I'm thinking of something like this:
While Nolan talked about Blade Runner being an influence on BBegins, it was more so the feel and detail. For the reboot, I think they should emulate the actual colour palette:
or something like so: (Shanghai)
I think something like this would retain the sleekness and modern feel of TDKT while distinctly breaking away from it with a different colour palette; one that matches this potentially shared universe.
One might say that what I'm describing here is merely the Arkham videogames; but for some reason I never liked the style of those games other than the trailers. I think it might have something to do with the ugly lighting in the actual gameplay and the overall art direction, not the style/colour palette.
