yes and i felt like i have be gutted after first see it . but not until the next day do i begin to see the true brilliance of this creation . i would not repeat much of what have already be say by those who appreciate the film and but there be one new area i want to touch on . spoiler why exactly do the teacher put the broken glass in the student pocket . most reviewer have note that it only reflect her cruelty and reaction to an unsatisfactory performance . i must disagree . watch the scene again . huppert be move to tear a she watch her student playing on stage . the student be quite an expressive girl ( cry and vocalize her fear ) just the opposite of huppert character . there be a scene later in the film and after the girl be injure and when huppert discuss the accident with the girl mother . the mother and visibly upset and state we give up everything so she could study piano and huppert immediately snap you mean she give up everything and do not you . so it be my thought that huppert be simply save this young expressive student from her own destiny . she do not want the girl to end up like her and repressed and harden and condemn to a life of recital . gradually kill the soul in the pursuit of perfection . maybe she saw herself on the stage year ago and before thing grow bad . maybe she wish she have escape when she be that age . be she ruin the student life and or simply free her . for me and that realization make all the difference in what i experience through this film . brilliant .
