I cannot believe this film is only rating 5.1! I thought it was a gripping, gritty and realistic descent into the sort of nightlife madness which comes along once in a while when people are determined to push things to the edge of the envelope. Fragile mental states are exposed, as is the inevitable questioning of the worth of everyday reality when one enters those altered states and environments. What drives these characters to do what they do? Is it worth it? What does it cost them, etc? The cinematography and direction are both outstanding. As are the characters and the acting. In short, I loved it!
