What I liked about this picture: the cool camera-work (airport lounges have rarely been as attractive, and there are evocative scenes in toilets and bedrooms); the music, always urgent and involving even if it owes much to Bernard Herrman; the identity of the transsexual character is well integrated into the story, not an add-on (I thought of Jaye Davidson in The Crying Game).
What I didn't like: the red herrings in the story line, meant to throw us off the scent but only serving to annoy the viewer; the large number of characters that makes following the plot all the harder.
What kept me watching was Victoria Abril, playing the detective's wife with a panache that made me regret she has not made more films we can see in North America.
