Suggest me something different

After watching shit ton of movies.. I'm kinda bored with our typical action/sci-fi/romcom/feelgood/comedies and want to watch something related it the old west or mafia or those typical de niro and al pacino movies.
I have no idea as i haven't watched many movies of that kind but I'm looking for movies that are sort of "taxi driver" or "Django unchained"
