The least successful film in this series was directed by stylemaster (and content-underachiever) David Fincher. Ripley, the only survivor of her past mission, awakens on a prison planet in the far corners of the solar system. As she tries to recover, she realizes that not only has an alien gotten loose on the planet, the alien has implanted one of its own within her. As she battles the prison authorities (and is aided by the prisoners) in trying to kill the alien, she must also cope with a distinctly shortened lifespan that awaits her. But the striking imagery makes for muddled action and the script confuses it further. The ending looks startling but it takes a long time--and a not particularly satisfying journey--to get there.
