The style 'film noir' has dark elements in its concept. When you translate it into English it's something like black/dark movie. In these types of movies, there are many murders in the back streets, intrigue between couples, and pessimism is always there throughout the movie. In short, these movie types weigh people down!
I have to say this, these movies in the list, some of which date back to the 30s, are still considered masterpieces and are adored by the audience. If you're bored with the classic Hollywood movies, these suggestions will make you more than happy. Enjoy the list.
