Milla Jovovich (looking incredibly sexy, might I add) is an amnesiac who unwillingly becomes part of a group of commandos sent to a large underground facility to destroy a sentient computer.  Unfotunately, what they don't realize is that awaiting them are hordes of the living dead who are hungry for human flesh!  Action/horror film directed by Paul Anderson mixes in elements from Cube, Ghosts of Mars, and Day of the Dead, and is never entirely successful, due to some bad acting (Jovovich, surprisingly enough, being the exception), a grating industrial musical score, and zombie shootouts that aren't directed with as much flair or intensity as you might expect.  Still, there are several standout sequences that are tense and thrilling, particularly a scene where approaching lasers try to make mincemeat out of the team inside an enclosed hallway, several exciting fight scenes against zombies, and the suspenseful finale that pits the survivors against a monstrous genetic experiment.  Definitely recommended to genre fans, and once again, Jovovich just rocks in this movie.
