Underrated horror sci-fi

Rating: 8/10 (25 April 2003)

I have watched this movie twice, and both times i found it interesting and scary. I know that it could have been better if this.. and that, but i cant help liking this movie anyway.
Now to the good part:

It is a horror movie without aliens, this is the best part, there is absolutely no aliens. I wish there were more of this no aliens sci-fi movies.
Most of the main characters get killed, thats right, only a few survive the mission.

Design of the spaceships is beautiful, and the filming is great.
I simply can't help liking this movie a lot.
This movie get 8/10 from me and is one of the best horror sci-fi movies i have seen.
