Disturbing and disjointed It's impossible to talk about this movie without mentioning the ending, so I've included one spoiler-free review for people who intend to see it. Do not read the second review if you are one of the latter category.
SPOILER-FREE REVIEW
The less you know going into this movie, the better, but generally it deals with the complicated relationship between two adolescent sisters, one strikingly attractive and undergoing an initiation into adult sexuality via a persuasive and manipulative law student (but I repeat myself), the other overweight and cynical, observing her sister's experiences with alternating envy and contempt. It's pretty turgid going for the most part, and its treatment of sex leaves one a little queasy, but contains some memorable characterization and at least one very startling twist in the narrative that make it ultimately worthwhile. Rest assured you will be wide awake when you leave the theater.
SPOILERS GALORE
I was really very tired of this movie by the time the final sequence came around. I found the dialogue overwritten (and overabundant) and the characters undeveloped, and the whole thing dragged itself along at a maddeningly slow pace. The actors are brave, and they do the best they can under Breillat's incessantly voyeuristic gaze which, if nothing else, evoke the carnality and emotional maelstrom of adolescent sexuality quite well (despite the aforementioned leaden dialogue), but in such a clinical and dispassionate way that one feels bad for the actors not because of the explicit nudity and sexuality, but because the inertness of the presentation sucks up all of their emotions and makes you feel as if you're watching the characters through a cage. This is not necessarily a bad thing, but it's very uncomfortable to sit through.
THEN comes the final sequence, presaged only by a vaguely ominous long highway driving sequence that carries on for several minutes, perhaps so that the audience will sympathize with the characters and nod off. It has previously been established that the mother is not used to driving, and the trucks bearing down on her at top speed suggest that a car accident is in the cards. Instead, they pull of the highway, and the audience relaxes. And then comes as shocking an explosion of violence as I can recall seeing in any movie.
In the context of all that comes before, it feels like a cheat, and my first impression was to say, "What a gimmicky cop-out." But it can't help but stay with one, and I am hard pressed to find a film that reproduces as effectively the shocking suddenness of death, which often DOES come out of nowhere as it does here. It's a shattering, nightmarish and profoundly disturbing scene, which trivializes all that comes before it (although much of it seemed pretty trivial to begin with). The coda vitiates the impact somewhat (it's implausible and considering what came before, leaves a bad taste in one's mouth), but without this final sequence I wouldn't recommend this movie to anyone I know. Breillat pulls it off with a flourish, but between her calculatedly callous treatment of the characters, her tedious dialogue and the fact that as effective as the ending is, it is still a gimmick, I have some reservations in extending more than modest praise.
