The earlier film by Julio Médem (Lovers of the Arctic Circle) is a prelude to the kind of cinematography that this Spanish film director/writer presents here. I have read most of the other comments, but they don't do justice to it, mainly because of the lack of understanding the original tongue of this film. The screenplay is excellent, full of metaphors and a rich use of very carefully chosen words. People who consider this film just an excuse for depicting sex scenes as the highlight of the movie are pretty much clueless. It is more than that, it is the complex storytelling that tangles the characters in this movie and the way that is told. Compelling and breath-taking. A must see.
