An exercise in futility.
This film is like two films in one. The first half of the movie (in France) is wonderfully taut and suspenseful. We wonder about the motives of the characters. The second half (in Macau) is filmed like an amateurish indy film. The ending is a frustrating exercise in disappointment and need to be explained away only by watching the interview with the director (on the DVD). I borrowed the book to compare the endings and think the book ties up the loose ends better. All in all a rather frustrating and meaningless movie after the suspense in the beginning.
