One difference between film noir and more straightforward crime pictures is that noir is more open to human flaws and likes to embed them in twisty plot lines.
Roger EbertHow quickly do we grow accustomed to wonders. I am reminded of the Isaac Asimov story Nightfall, about the planet where the stars were visible only once in a thousand years.
