Crime film genre (4)
I believe the answer is:
noir
'crime film genre' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for noir that I've seen before include "Dark in France, like brooding films of 40s and 50s" , "film genre" , "Film featuring bleak settings and cynical characters" , "type of film" , "(Of film or fiction) with bleak settings and cynical characters" .)
