What is what does noir mean?

Noir is a French term that literally means 'black' and it is used to describe a style of film or literature that portrays dark and pessimistic themes. It was a popular style in Hollywood during the 1940s and 1950s and typically focused on criminal activities, distrustful characters, and bleak settings. The genre often featured a disillusioned protagonist who battled with moral dilemmas and inner turmoil. Noir also emphasized the use of black and white cinematography, shadows, and low-key lighting techniques to create a moody and atmospheric feel. Today, noir has expanded to include other art forms such as comics and video games and continue to inspire contemporary works.
