The songs are sappy (apart from Barry Manilow’s one good song here, Marry the Mole); the hero and heroine are bland master-race specimens; and some of the pastel effects are ugly and tacky. But most of the animation in this Don Bluth feature is fairly nice, if not exactly memorable to adults who’ve seen it all before. Kids should like it fine, I suspect. Gary Goldman codirected, and among the actors supplying the voices are Jodi Benson, Carol Channing, John Hurt, Gilbert Gottfried, Kenneth Mars, and Loren Michaels. (JR)
