Michael Fassbender's commitment is overwhelming. He must trust his director, implicitly. Good for him. Very rarely we've been exposed to so much sex without an ounce of erotic flavors. Well, that was not the intention, clearly. This is a remarkably serious film about addiction.To make matters even darker I had seen Michael Fassbender as Jung only a few days before. What an actor! Now I feel I'm as familiar with his anatomy as Mrs. Fassbender must be. I must admit the film stayed with me because within its mathematical coldness there is a palpable element of horror. Was it me or Fassbender shows the face of death in one of the many sexual occasions? Chilling really. I will take my chances and recommend it, as long as you don't take your children - I guess you can't NC17 - or your grandparents.
