I was disappointed by this movie. The meaning in German Wolke 9 or Cloud nine means that a person is full of happiness through being in love and passion with another person, hence sailing on Cloud 9. I don't argue that this could not happen to a well mature couple, but it was lacking in this movie. From an aesthete point of view it was not necessary to show closes ups of the aged bodies. I remember the movie Cocoon, which had a lot more sense, action and humor, also relating to older couples that enjoy or rediscover love and passion. Even the few spoken dialogs were motionless. I believe that the story had more potential than it showed. Well, just my opinion.
