Yeah, I have considered it, and in fact I know that is actually the real reason, but everyone here seems to think that it has something to do with absolute realism. Of course, when realism works against them, they resort to "Well, it just LOOKS better", which reveals their true stake in the argument and that it is all subjective.
I like black and grey Batman, and I think black and grey Batman will not only work on film, but in 'Nolan's universe'. Somehow that makes me some sort of zealot. I think people need to step back and look at what they are arguing about.
