You won't find a better horror/sci-fi movie released in the last year or several years, with the exception of the only other movie to do horror justice in the past decade; The Descent. This movie looks great, and it builds a very tense atmospheric environment that keeps you on the edge of your seat and afraid to keep watching. The creatures have been done to death but are nonetheless effective, and the twists throughout the movie add a psychological element to the movie that makes the ending not entirely predictable, even for a hardened movie buff like myself. This was, hands down, the best movie released in 2009 that no one bothered to see.
