The Piano Teacher (2002)

Human Drama - French film... Plenty of explicit sex and some violence. Ambitious and slightly disturbed piano teacher/concert pianist punishes her students to excellence. She appears cruel and unfeeling. A bold and musically talented male student falls in love with her and pursues her. The teacher reveals her strange and unusual sexual preferences (to the boy's shock and dismay). Good psychological study and superb acting, but this story is not for everyone. The ending was uncertain. 2 hrs 5 min
