You folks are crazy
This movie is terrific. Stephen Rae is heartbreaking. I suffered at every moment right along with him. Stewart Gordon is unflinching and the whole movie is cringingly honest. It's a horror movie in the most humanist sense, occasionally managing moments of absurdist comedy on top of it...my suspicion is that it otherwise would not be watchable.
The film is dark as hell, but not mean. All the meanness comes from its central characters.
