“What are you doing?” It’s a question asked a lot throughout "The Blue Lagoon," "Grease" director Randal Kleiser’s 1980 adaptation of the early 20th century story of shipwrecked cousins growing up in isolation on an island. The film, which Roger Ebert called “the dumbest movie of the year” was a box office success and critical failure, generating controversy for its sexual content featuring a 14-year-old Brooke Shields. Watching the film today, “what are you doing?” is a resonant thought. The horny, expository melodrama makes for an awkward watch that becomes more interesting when considering the context of its star.
