Shades of Grey.
Sleep Always is a movie about a man, Frank, that is obsessed with a homeless women, Nada. What separates this movie from most is that it asks more questions than it answers. Is Frank's life so mundane that he can only be infatuated by Nada? Who and what is Nada, and why is she found so captivating by Frank? At what cost is a relationship with Nada worth pursuing? Who is Frank's neighbor, and what is he trying to protect Frank from? The story is presented in a slightly non-linear format, so it is up to the viewer to decide what is the past and what is the present.
This is a daring film, shot on a daring format, by daring filmmakers. Not often does a film respect its audience enough to forgo all the answers. As an old proverb goes, "You are what you think about all day." Nada becomes Frank's obsession, and it is up to the viewer to decide where Frank ends and where Nada begins.
