Horror in Space, that's what this is. It's a space monster movie, and the thing is, if you see Aliens, or most of the other Alien related films BEFORE you see this one, you're going to be expecting something completely different.

But what you have is a horror movie set on a space ship with an atmosphere so thick that you could cut it with a knife.

You can taste the eerie tension when you watch it...and, at least in my eyes, that makes it better than the over-the-top Space Marines that you see in the later installments.

And, no questions are answered. There is no broad sweeping mythology. There is only the movie, there is only the monster, there is only the fear and tension. But that is all the movie needs.

It's just science-fiction and scary. It's a brilliant merger.

But, don't listen to the people making it out to be more than it is. It's really ONLY a horror movie in space and nothing more. That doesn't make it any less enjoyable, but it does make it completely confusing when you read reviews that make it out to be more than an exceptional monster movie.
