From the time the protagonist watches the video nasty that leads her to believe the actress is her long lost sister, the film gradually devolves into a psychedelic nightmare and never lets up. You can literally feel the protagonist spiralling down into a dark tunnel of madness and despair, and the climax is both immensely shocking and satisfying. The film serves as a great social commentary - who are the people who watch video nasties the most and are most likely to be affected by them? No, it's not the general public, but the censors who review them, cut them and make them fit of public consumption. In the end, you cannot help but wonder whether you should categorize this film as a video nasty too! Highly recommended.
