I saw that movie many times when I was growing up in France. It is part of this special set of "comfort" movies that everybody who grew up in France has probably seen many times as well... these special movies would be shown on french TV at and around Christmas. If you are interested in better understanding the french culture, you must see it, independently of its artistic merit (even though it is pretty high, in my opinion). Moreover, Catherine Deneuve is the most beloved/respected person in France (and the coolest thing about her is that she is still human, flawed, aware of it, and eminently approachable). Ebert is right when he says that she is ageless. The baking scene is a classic and the turning point in the movie. By the way, other "comfort" movies include the 5-DVD boxed set of Angélique adventures, recently released by RusCiCo (every french boy was in love with Michèle Mercier), any comedy by Louis de Funès (the epitome of french comedy for the whole family), and so forth. These are fantastic movies to be truly enjoyed, so I failed to understand the criticism of some about the fact that this or that scene would not be "believable".
