There's often something creepy and inhuman about people who have had too much cosmetic surgery, which may be why surgically enhanced stars like Pamela Anderson Lee and Carmen Electra look less like sexy women than grotesque caricatures thereof. Electra's slightly robotic looks, not to mention her inability to act her way out of the proverbial paper bag, work against her latest direct-to-video film. But The Mating Habits Of The Earthbound Human probably wouldn't work even if writer-director Jeff Abugov had cast an actress in her role, rather a vaguely frightening eternal starlet. A gimmicky pseudo-documentary about human mating habits—illustrated by the courtship and eventual mating of a human couple (Electra and MacKenzie Astin) and narrated by droll space alien David Hyde Pierce—the film stretches its unpromising one-joke premise to an excruciating 90 minutes. Electra and the bland Astin make for a less-than-scintillating couple, and the cheerfully inane script by Abugov (Roseanne, Grace Under Fire) seldom strays from sitcom-shallow predictability. Just about the only thing that sticks out about Mating Habits is its bizarre climax, which takes place in an abortion clinic; it's an exceedingly odd ending to a film that's otherwise mind-numbingly generic.
