An experimental film that explores the different aspects of love (don't get confused about the "Sex" word on movie's title). No real plot, but many assembled sequences which creates an strange (and interesting) atmosphere.To really enjoy the film you should get carried away by his evocative images, echoes of a past that will not return (in that sense the film is truly unique). Diametrically opposed to the actual concept of filming, it was also an unusual film in its time, and today is a gem that should be revisited.
Special mention to the beautiful soundtrack, one of the first great works of Vangelis, where is outlined his future sonic palette. Also the presence of the gorgeous Jane Birkin is very enjoyable too: She looks painfully beautiful.
Well, you should abandon any prejudice to enjoy this film, and of course, even doing that, it will still not be appreciated by many. But believe me, actually there are no films like this one who remember us that cinema is much more than a marketing plan. Enjoy Sex-Power. Thank you very much for reading the review.
