At 5x2 we see the course of a relationship from end to beginning. The reverse chronology of events is now a well established editing technique which almost always works and intrigues the viewer.
The personalities of both Marion and Gilles are established fairly quickly, but the reasoning behind their actions is usually explained at a later time. In fact, this shows how well written 5x2 is, because throughout all five episodes the characters of the protagonists don't change, their behavior has changed due to actions of the other part.
Both actors deliver high caliber performances and their faces write perfectly on the screen. They do create a chemistry when needed (and a lack of again when needed). Can you believe by the way that beautiful Valeria Bruni is forty years old?
The vintage Italian music adds color to the story and Ozon shows he is an accomplished director. As the movie ends he gives us one of the most idyllic scenes ever filmed.
