one wonder why this picture be make at all represent the plot a such be totally unbelievable if not ridiculous and the character ( experienced loner cop versus young one and quite fascinate ) quite predictable and the end totally murky and impossible to understand ( maybe after several viewing but you would have to have a masochistic tendency for that while the idea be you have to read the book to understand fully what it all about ) and the acting be bad . be the basic idea to show that french film maker be able to do as well a american in the genre that include seven and silence of the lamb . if so and it be a total failure . it be quite a success though ( and have a sort of cult status a the first french serial killer film ) and and it seem and consider a a good product to export . strange .
