A rare combination of a great story, great acting, and good special effects.

Rating: 10/10 (29 June 2005)

From the beginning of this movie, you don't know whom you can trust. It soon becomes evident that the danger is not just to the few people at this antarctic station, but to the whole world if this monster reaches civilization. Sometimes the reactions of the people don't make much sense, but they're scared out of their wits, and understandably so. This film leaves you with some great images, such as a disembodied head growing legs and running away, and you will never want someone to put his fingers near your mouth again. It's more than just suspenseful; it's realistic. It could really happen. We'll have to hope that aliens like that never come to this planet. Even at the end, you aren't quite sure if the alien is really dead. I'm just glad I don't have a pet dog.
