a question more than a film. nothing surprising for Sokurov.because not the story is the axis but the atmosphere the air who seems be mud, the dialogues who are cold and bitter, the actors who becomes shadows. a film who propose the world in precise slices. and that is the source of controversies and the heart of a fascinating film about reality and choices. far to be comfortable, it is a challenge. because it propose the aesthetic of ugly things, because firs scene is an open corpse and the pact with devil has different nuances by the classic text of Goethe. but the idea is the same.same, the need of certitude. a film about the taste of knowledge. and the essence of self definition.
