One of the best documentaries I've ever seen. It really changes the way you think about homelessness. The cast of real people in this film are refreshingly charismatic. I really didn't expect to be blown away by a film like this, but trust me it's really an excellent work. The fact that Marc Singer had the balls to venture into the cavernous abyss of the Penn Station tunnels for such a long period of time to make this film makes it even more admirable. For me this film to me really has taken the genre to its highest level because the director actually lived and survived with the cast of the film and literally became homeless himself, not to mention letting them take an active role in making it in terms of production. I really can't think of a truer way to shoot a documentary like this one.
