It's a little jarring to see these two one-time emblems of rebellion in the roles of aged parents who just didn't understand, but of course that's part of the film's point. Youthful impudence is a great and sometimes useful thing, but it is, alas, practically unsustainable... These characters, and the actors playing them, get it very, very well. It's in the way that Depardieu and Huppert can convey an aspect of phenomenological rue that gives this sometimes muddled movie its ultimate value.
