Crime-drama genre (4)
I believe the answer is:
noir
'crime-drama 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 "(Of film or fiction) with bleak settings and cynical characters" , "Kind of dark film" , "Film featuring bleak settings and cynical characters" , "type of film" , "Dark in France, like brooding films of 40s and 50s" .)
