Even when the characters are together in the same scene, they are often shown individually and not together. They are only framed together during the few times that they share intimacy. The austere form and light touch of this film hides the furious emotions hiding just below the surface - too far below the surface for me. I couldn't feel for them because they would not allow us to know how they were feeling. In this respect, the film is too ambiguous, too abstract.
Films are usually about the transformation of the characters as they learn from their experiences.
Une Liaison Pornographique is about a woman and a man who do not change, and will not allow anybody to see them as they really are, which is truly sad. Not only have they kept each other at a distance, they keep the viewer at a distance also.
