Its difficult to imagine how this film could have won an award in any category. The first 20 minutes are indeed intriguing (up to the event), but then we are treated to gratutious sex, which may have been included to mask over the lack of plot, character development and amateurish acting (at first i thought the police detective was attempting comedy). Its quite simply a poor film masquerading as some form of out-there arthouse tosh.
The suspense is intense during the last 5 minutes, as you attempt to make the decision to yawn or leave.
