The Documentary that I would like to recommend is Dark Days directed by Mar Singer. Dark Days tells the story of homeless people that live in the tunnels of the New York sub way. There is no law no convention and no sun light int those terrifying depths, but the people that live there seem to appreciate the isolation and the life style associated with it. Aside from perfectly capturing a unique and completely engrossing way of life, the film is beautiful. Every shot is carefully framed and the subject matter begs to find a screen. Dark Days is a must for any fan of Docs.
