I totally got surprised by this film, in a positive way! I haven't read the book, so I can only rate this film on it's own. I enjoyed acting and the story. I would sum it up as a dark comedy, about life, relationships, finding your own way in life... It asks questions which I sometimes ask myself, so I very much enjoyed it.
I have to be honest and disagree with many of the reviews here. I found the book to be awfully pretentious and very cold, not great at all. The film, on the other hand, managed to find some sort of emotional heart in the material and was a rare case of the movie adaptation being better than the book.
Da gusto verla aunque sea por ir recordando el libro. Por supuesto que el libro tiene mucho más contenido que la película que sólo son recortes aleatorios, sin embargo el arte de la película vale la pena y creo que las actuaciones sí captaron el espíritu de la escritura original.
