Chris Underwood’s review published on Letterboxd :
Beautifully shot and executed, this is art house depravity of a very high order. Kidnap, torture, humiliation, forced sex and much bondage, this is one of the very best of its kind. Starts predictable enough but does not let up for a moment and has many surprises. An escape and seeming rescue goes terribly wrong and a young suicide couple find that life can indeed get worse. Unusual in that there are so many exterior sequences (sex on a rock face anyone? Perhaps a whipping instead?) Completely over the top and yet always believable this is a stunning example of Sadean cinema that I rediscovered whilst researching for my list of such films.
