How is Sin City described in Frank Miller’s Sin City the Hard Goodbye?

Sin City, as the popular name implies, is marked by corruption. The city's industries are underground clubs, for-hire corrupt police, and prostitution. The desert setting adds to the film noir feeling, creating a luridly hot environment, where the characters roam at night and sleep through the day. Sin City's dryness also functions as an objective correlative, a physical manifestation of the character of the city itself, morally desiccated. When there is a rain, it is a downpour. The setting is high in contrast: either arid or pouring, black or white.
