A vivid portrayal of urban loneliness, not for the homeless or the truly destitute but for the ordinary. The cinematography is first-rate; metallic yellows and greens give a vertiginous, hallucinogenic feel to the club scenes. The excellent Chemical Brothers soundtrack is used to startling effect, building an inexorable tension right up to the finale. The unexpected outcome of this harsh and sometimes despairing film is the possibility of love and of redemption. I switched it on out of curiosity and ended up mesmerised.
