This is as European as you can get with a slasher movie (many similar movies seen in the past). As most European movies are these days (Even Gaspar Noe's infamous 'Love' had only topless female nudity and just dicks in closeups,squirting,etc) ,it is a gay's christmas delight. The lead actor seems to have been picked solely for his fitness and readiness to go completely stark naked (for the last 40 minutes of the movie).Funnily,the other male actors look normal unlike the model-body,six-pack leading actor.The female nudity is limited to fleeting topless and one rear-nudity shot.This is so sexploitative that at times it is stunning and actually distracts the viewer from the movie.French are obsessed with the male genitals and here you have it all in its glory for such a lengthy time.
Having said that it is an effective thrillers with the leading lady very good in the role.If swinging dicks disturb your senses,watch the movie after a drink!!
