HORRIBLE MOVIE, NEVER SEE THIS MOVIE
You're kidding?
i really liked this movie i would say give it a shot at the big screen or cheaper theater but worth seeing on big screen
Great movie & storyline! Keeps you on the edge of your seat!
scary as hell.kept me at the edge of my seat wondering whats next.i would definately recommend this flick if you like a good sci fi horror.
One of the best sci fi /horror movies to come out in a VERY long time. A blend of aliens,the cave and the descent. Excellent, must watch. Dont read any reviews, people will spoil it for you.
Is it just me or do all movies with Dennis Quaid seem to turn out good? This movie impressed me beyond belief. I went in thinking it'd be some cheezey horror cash-grab, but instead it had a story that kind of combines Sunshine, Event Horizon and Titan A.E. Definitely worth seeing in theatres! 4-stars
Well executed and engaging. Good atmosphere and effects. The ending could have been thought out a bit better though. Keeps you wanting to know what happened at the end.
Scary As Hell!! Way Better than I expected. One of the best movies this year. And I've seen a lot.
Well done movie that steals from almost every sci-fi movie ever made.Some scary moments and creatures thet have "fleshy" appetites.
