Film noir is often described as essentially pessimistic.
The noir stories that are regarded as most characteristic tell of people trapped in unwanted situations (which, in general, they did not cause but are responsible for exacerbating), striving against random, uncaring fate, and frequently doomed.
The films are seen as depicting a world that is inherently corrupt.
Classic film noir has been associated by many critics with the American social landscape of the era—in particular, with a sense of heightened anxiety and alienation that is said to have followed World War II.
In author Nicholas Christopher's opinion, "it is as if the war, and the social eruptions in its aftermath, unleashed demons that had been bottled up in the national psyche."
Film noirs, especially those of the 1950s and the height of the Red Scare, are often said to reflect cultural paranoia; Kiss Me Deadly is the noir most frequently marshaled as evidence for this claim.

Film noir is often said to be defined by "moral ambiguity", yet the Production Code obliged almost all classic noirs to see that steadfast virtue was ultimately rewarded and vice, in the absence of shame and redemption, severely punished (however dramatically incredible the final rendering of mandatory justice might be).
A substantial number of latter-day noirs flout such conventions: vice emerges triumphant in films as varied as the grim Chinatown and the ribald Hot Spot.

The tone of film noir is generally regarded as downbeat; some critics experience it as darker still—"overwhelmingly black", according to Robert Ottoson.
Influential critic (and filmmaker) Paul Schrader wrote in a seminal 1972 essay that "film noir is defined by tone", a tone he seems to perceive as "hopeless".
In describing the adaptation of Double Indemnity, noir analyst Foster Hirsch describes the "requisite hopeless tone" achieved by the filmmakers, which appears to characterize his view of noir as a whole.
On the other hand, definitive film noirs such as The Big Sleep, The Lady from Shanghai, Scarlet Street and Double Indemnity itself are famed for their hardboiled repartee, often imbued with sexual innuendo and self-reflexive humor.
