It is inspired by the life of Madame de Maintenon who created with the help of Louis XIV a school for young girls. This could seem dreadful and it is not. This movie is something inbetween Full Metal Jacket (First part) and Barry Lyndon (Second part). It is more than the story of young girls. It deals with religion, the duality of (wo)man. It is beautiful and savage and the actresses are great (ever heard of Isabelle Huppert ?). Hope you can watch it in French because the language is perfect. Definitely worth looking. I just hope this movie will be screened all other the world. Maybe a palme in Cannes will help but I do not think Mr Besson will like that sort of movie ;-)
