1. "Past certain age, a man without a family can be a bad thing." That applies to women as well. I saw erotic fantasies, naive jealousy and suppressed desires of this middle-aged woman, in addition to the depressing dilapidation and disconcerting music.
2. The narrative delicacy (or should I say consecutive nuisances) was undisturbed until the end, which makes a quite uncanny movie. However I have to say importers/translators have a talent of ruining surprises.
3. Crime fiction writers might be the most pathological occupation in the world, combining sinuous maneuvering of a criminal and unsteadiness and insecurity of a writer. Ah, maybe the director of a movie about a psycho writer conducting nasty businesses can be worse.
