i be not sure how related they be and but i be almost certain that lose and delirious be a remake of this movie ( or the story that it base on ) . very similar plotline and and even some of the scene and set seem to be very and very similar . lose and delirious be actually a much good movie and so see that one instead . this one move very slowly and but be a late 60 french movie and that be to be expect of the style . tell in a retrospect from the perspective of one of the girl revisit the school . the editing of the flashback with the current scene be a little bit confuse at first and particularly since the audio from each overlap ( ie and hearing flashback while see the present and vice versa ) . also and the girl be a bit old to think that they be in a boarding school . finally and not much character development to even get you attach to the movie .
