Sexual Chronicles of a French Family

I don't want to get into a discussion whether the explicit display of sex - the term 'soft porn' comes to mind - is a good or a bad thing, or necessary or not. I don't mind. The movie starts with a good idea and promise. The teenage son of the family is caught masturbating in school. The mother takes it rather easy and doesn't make a big deal of it, but she starts to think about her own sex life and that of her widowed father in law. I thought that this would lead to the uncovering of suppressed sexual desires of the parents and grandfather, and that this could cause some frictions or maybe hurt feelings somewhere. It holds vaguely with some of the characters involved, but the only real forward going story is that of the son having his first time experiences with a girl from school.

Unfortunately, there is not much left of the film when you take the heavy breathing scenes out. You can write the entire plot on the back of a postage stamp. For almost an hour and a half, the movie shows a family of three generations in which most of them have a rather fulfilled sex life. This is nice, but why do I have to watch them doing it?
