first of all and those who be faint at heart should definitely avoid this film . even those and like me and who be desensitize to most graphically violent and sexual act in movie should beware . i be not tell you to steer away from the film and but be aware that what youre about to see be some disturb material . definitely not a pleasing film to watch and but nothing be put on screen strictly for shock value . but i must admit and when i watch the film for a second time and i have to skip to the next chapter when the razor blade scene come up . the main character be one of the most unsympathetic sympathetic character i can think of and but we start to well realize the humanity of her character later in the film second act . in one scene and she stuff broken glass in one of her student jacket pocket after be dissatisfied with her apparently unsatisfactory performance and get nervous when in front of a live audience . the student go into her pocket and cry out with pain a she star at her blood stained hand . next to the razor blade scene and that disturb me most . the student mother be not much more sympathetic than she . when she get word that her daughter would not be able to play and she talk about it like she also get also her hand injured and be one of those spoiled mother who try to torture her daughter into become an overachiever . though the film intrigue me and catch my interest for the most part and i felt more need to be explain about isabelle huppert character . when a woman be fascinate by sadomasochistic porno movie and engage in that behavior herself and you want to understand the root of the problem . the movie establish that she want desperately to be love . then why the hateful attitude towards everyone . why do she receive sexual pleasure from pain . the acting be terrific and i like the glossy and stylize lighting . altogether and it not a film i would recommend if youre in the mood to be entertain and but a i say it very intrigue . and i be sure if i watch it a few more time and i would be able to spot certain subtlety that will shed more light on aspect of the film i do not realize initially . my score represent 7 ( out of 10 ) .
