A submarine with a coed crew encounters an obscure sea monster in a lousy, cliche-ridden thriller, scripted by Lewis Abernathy and Geof Miller in an apparent effort to emulate Alien and the original version of The Thing, and directed with dutiful clunkiness by Friday the 13th’s Sean S. Cunningham. Among the actors who repeatedly get wet are Nancy Everhard and Miguel Ferrer. (JR)
