I saw Le temps qui reste not so long ago by the same writer and director as Swimming Pool, which was also very interesting and unique. The story is about a homosexual photographer who finds out he has cancer and has about 3 months to live. It's a painful movie, but yet so wonderful at the same time... Ozon's definitely exploring the boundaries. I guess you have to be open minded to really appreciate this movie.
