What is one of the key characteristics of a film noir?

A key characteristic of film noir is its complex moral ambiguity. This genre often blurs the lines between right and wrong, presenting characters who grapple with ethical dilemmas and face situations where conventional morals can no longer be applied neatly. Protagonists in film noir are frequently flawed, and the narratives include elements of betrayal, manipulation, and existential despair, which contribute to a particular tone and atmosphere that defines the genre.

The use of moral ambiguity amplifies the tension and intrigue, captivating the audience as they navigate the dark and often cynical world the characters inhabit. This layered storytelling invites viewers to question character motivations and moral decisions, adding depth to the film's narrative.

Other options do not align with standard characteristics of film noir. Bright and colorful cinematography is generally contrary to the typical dark and shadowy visuals associated with the genre. Happy endings are rare in film noir narratives, which often conclude with an unsettling or ambiguous resolution. Limited character development fails to capture the rich, complex portrayals that are significant in this genre, where characters often experience profound arcs influenced by the moral dilemmas they face.
