Query: The joy of 70s films

Although the subject matter is risque, the cool, unstylised camera work and authentic acting make MAITRESSE a far, far better film than others in the "adult" genre. Barbet Schroeder cut his directing teeth on documentaries and it shows: the weird and extreme scenes hover between funny, frightening and banal - the audience isn't told what to feel or think, and have to decide for themselves. The whole affair feels real and human, and it's relaxed and unself-conscious in a way that modern movies, especially Hollywood films, just aren't anymore. Bulle Ogier, as the maitresse, is terrific.
