Re: BATMAN REBOOT: your personal preferences?
I'd love to see a very dark grim Gotham. Have it constantly be raining, criminals running the streets, lots of pollution and zeppelins. Something similar to Sin City, Watchmen, or Blade Runner. A very noir-ish tone. Where all the criminals wear fedoras, smoke, and use tommy-guns. Maybe even have it take place in 1940s.
Have a very dark a dingy desaturated Gotham, with bright, eccentric villains to contrast it.
