the developing prose of the story with the abstract implying ideas (specially the suggestive narrative story telling) that synchronize in the rhythmical scenes and intense drama of passion, along the scripts playing with language from polite to vulgar.... and then there's how it's filmed rich in emotion from all the characters even by the by-standers, with an almost accurate period movie where past early after turn of the 20th century we get to glimpse travel.... but at always this film remain or kept itself simplistic in style despite the intricate weaving and integrating of the art of old world romance, dark mystery movie and sarcastic humour in suppress comedy, while the drama of human conflicts and aspirations are all in one (it all depends on your receptors at the time of watching)... or very accessible to watch...

what really is surprising and very much what makes treasure of the film is between Olivier Martinez and Aitana Sanchez-Gijon chemistry and real genuine passion, that's hard to fake sensual romantic intensity, as much as naturally born sexiness, sex appeal and good looks cannot be faked either....
