This is the world discovered and illuminated by gonzo documentarian Marc Singer, who spent a good part of two years living with and chronicling the lives of a half-dozen tunnel dwellers for his remarkable first film, Dark Days

Moving and memorable.

The lives of these people inside their shacks are full of surprises as well as grim confirmations, but the things we don't know about them also significantly shape our experience of the film.

Dark Days is well-paced, knowing when to ramble and when to pull you up short. Great editing. Great choices of which stories to tell on camera.
