Babylon Berlin is a recently added Netflix series out of Germany. I'm only a couple of episodes in, but so far, highly recommended. Set in Berlin in the 1920s and filmed in the Noir style. About a vice cop chasing the Berlin Mafia.
Just very well done cinematography and script. It has both German and English versions. Having listened to them both, even if you don't speak kraut, I recommend setting it to kraut with English subtitles. It's very much like Seven Samurai in that the dubbed version loses something in the translation.
