This was promoted as a film to take your kids to for the sex education you didn’t have time to give them: as two adolescent shipwreck survivors (Brooke Shields and Christopher Atkins) romp around a tropical island, director Randal Kleiser employs continual cutaways to a Greek chorus of approving wildlife to demonstrate how fresh, right, and “natural” it all is. But if they were my kids, I’d rather have them think sex is dirty than that it’s stupid, which is the line this witless, mawkish film puts across. The pretty-pretty visual style is evidence of a close study of Days of Heaven, as well as a complete misunderstanding of it. With Leo McKern and William Daniels; photographed by Nestor Almendros, forced into garish effects far below the level of his talent (1980).
