Sweet and charming, but also a trifle predictable, French Postcards is an amiable little coming-of-age comedy that will beguile many. Even those who find themselves not so easily beguiled should find Postcards an agreeable little affair; it's hard to dislike a film that's as harmless as this one. Created by Willard Huyck and Gloria Katz of American Graffiti fame, Postcards has that same interest in the magnified importance that teen-agers and young adults feel about every little thing that happens to them, as well as the innocence -- soon to be lost as adulthood beckons -- that can still make tiny triumphs seem magical. A few things keep Postcards from being as good a film as Graffiti, starting with the simple fact that Huyck is simply not as inventive a director as George Lucas. Postcards also meanders a bit too much, and the sweetness at times becomes a tad cloying. Its cast varies, with David Marshall Grant and Blanche Baker fine but no more. Much better are Miles Chapin, Marie-France Pisier and especially Valerie Quennessen; special note should also be made of Mandy Patinkin's bizarrely amusing cameo. Location lensing is also a plus.
