leo carax have make 3 great movie represent boys meet girl and mauvais sang and les amants du pont neuf . in fact those film be not that great but it have the violence of youth and the beauty of juvenile wilderness . carax in these three movie be well aware of what cinema be and but he try to make his own vision of the art and without think about about all he have see and but use it and melt it into his time . pola x be a very different movie because carax make le amants du pont neuf and a monstruosity of 20 million dollar and a film that have destroy everything on it way . after such a movie you can not do another one in the same point of view . so leos carax have to change and and he do . the movie isn not as beautiful a it first and it more reasonable and no more studio and no more dreamed paris and carax have enter at last reality . it not clean anymore and it not poetic character . carax have become a romantic in the german sense of it .
