To be honest I had to go have a stiff drink after this film; I felt drained and my shoulders were knotted. I also had to talk the whole thing out with the friend I saw it with for a good half hour. Whatever else this movie is, it's not dull - you have to have respect for anything that produces such a visceral reaction, even if you couldn't claim to have 'enjoyed' the experience. (Anyone else I've talked to who's seen it has responded in much the same way.)
The reason the film is so powerful is not simply because it deals with unpalatable subject-matter like sado-masochism and violently dysfunctional relationships - that on its own would leave no defence against a charge of exploitation. It packs a punch because whatever her deeply ingrained character flaws, however reprehensible her behaviour (and at one point that's VERY), the piano teacher Erika always retains your sympathy - you never forget the type of influences which might have made her what she is, while scenes as subtle as the one where she walks down a street of shoppers, being casually bumped into without apology, remind you of her utter isolation. Isabelle Huppert's performance is as brilliant as it is uncomfortable and I can't even imagine how she might have wound down after a day's filming.
Appalling, compelling, horribly funny at times, but ultimately deeply despairing look at how people damage each other. View with caution.
