I just finished watching it right now. Remember watching it long ago. At that time, I wonder why I never thought what I think now.
The movie is just plain gore, and horror. In every scene, the concept of the inevitable shocker is presented. The style is typical for horror movies.
The story sucks.
The characters are said to be "professionals" but they don't behave like ones.
The sounds are shocking (Name a horror movie without shocking sounds).
The effects are pretty much okay.
The ending is horrible.
The idea that the shortest distance between two points is zero is pretty interesting though. But if their distance is zero, that could only mean that they are actually just a single point. That is since no two things can occupy the same space at the same time. I don't know. XD
Anyhow, if you want some time-wasting, sci-fi, gore, and horror movie, this one is the way to go.
