The movie is based on characters that originally appeared in DC Comics, and means to be funnier than it ever is. It almost achieves its comic goal in one scene in which Swamp Thing and Heather Locklear, as Mr. Jourdan's innocent stepdaughter, attempt to consummate a love that cannot be. The film is otherwise composed entirely of special effects that alternate with whimsy.
