Not a realistic depiction of sexual abuse in my opinion. Indeed quite possibly the least violent 'rape' in motion picture history. Granted, the 'attacker' is butt-ugly, but otherwise they might have been just some upscale couple role-playing, with the 'victim' overacting to make it appear that she's suffering. Don't be surprised if the whole effort has more the effect of arousing than making one cringe. (Is that a spoiler?)
I'm not sure how I can satisfy the length requirements of IMDb with this review since the film is just not good enough to inspire further comment. I'm in a bind so to speak. I suppose one could say it has more the feeling of a documentary than a stand-alone movie. According to Bill Zebub, the bonus material contains an interview with the actress that bears watching. (That can't be his real name.)
