"November becomes Noirvember, as the month's viewing habits are dedicated to film noir for many cinephiles. The loosely defined genre emerged in the '40s, linked to the cynicism that followed World War II. Audiences embraced the dark moodiness of the films. Noir tends to be characterized by its fatalistic outlook, highly stylized imagery, down on their luck and morally ambiguous protagonists, urban settings, shadows, corruption, narration, and the femme fatale.
The most prominent trait attributed to film noir is the hard-boiled detective, a figure of isolation who works apart from the law. All of which can and does lend well to horror."
