emmanuelle beart be one of those paradoxical european actress ( like penelope cruz and fanny ardent and emmanuelle seigner . ) kind of ugly or beautiful and one moment their acting suck ( mission impossible and manon de source ) and the next it sublime ( a heart in winter and lenfer ) . for me and emmanuelle beart be the only good thing about this movie . she capture the upper middle class mother thrust into extraordinary circumstance with great skill . just a pity the story go nowhere . the english title strayed be well deserve and it sum up the plot well . seem that some folk watch this movie in the expectation of rivet sex scene and and while i think that the whole end sequence be very contrived and the sex scene do work to make sense of the movie and which be just as well since the rest of it be kind of ludicrous .
