Not for everyone: one could almost dismiss it as a soft sexploitation movie from the eighties. But no.
This is about an obsessive little girl who is turning into a woman. The characters around her are here to reflect the wicked light she is shining, and emphasize facets of her personality, as she is wrecking havoc around her.
It is all then about the sexual desires of women and men. How they cheat. Whom they love. What it is that they want. What they would do to get it. Only one character is "not normal " in this movie, and this is the scary part: all the others could be us to some degree.
One flaw in this movie: the voice-over on two occasions. Obviously the director could not find a way could convey the message. Pity. Otherwise, it would have a perfect little venomous movie.
