Brilliant descent into darkness and despair.

Rating: Null/10 (10 May 2002)

This is by far one of the most gratifying sci-fi/horror films I have ever seen. What begins as a seemingly innocent and boring science expedition quickly degenerates into a white-knuckled frightfest, and the scares are genuine and continuous. Turn off all the lights, turn up the volume, and be prepared to have nightmares for weeks, if not months. This movie will scare the hell out of you.
