what a good movie I enjoyed it

This was a verry good love movie if u like horror movies watch this,10/10

I fell asleep, that should say a lot about the movie. Good start, boring after a while since you've seen similar stuff. Can't say so much more since i didn't finish it, I love adventurous movies with climbing or diving etc. but there wasn't much more than that. 3/10 since i don't wanna finish it.

Great movie wish there were a part 2! 5/5

why would you post the ending??? you jerk

great movie but do not watch sanctuary...

Good movie. I enjoyed it.

Okay movie,something to watch. Reminded me too much of a lesser version of "Descent." Not the worse movie in the world to watch but a bit mediocre.

It was ok but pretty predictable. Acting was fine.

Surprisingly well done.It's not no Descent 1,But i enjoyed it. Had to decide to believe the opening but overall good, satisfying entertainment. If you're in the mood for what you got excited about as a kid, this fits the bill w/pretty good effects, worth a watch...

pretty good action thriller and most of it was in the dark but turned out pretty good. worth watching.

great movie special effects were very good great acting 9/10

Not bad, but I was expecting better with all the comments bellow... 3/5

One of the most POOR movie about "caving" I have ever seen! Me and my mum (massive fans of horror genre) where bored to death when watching this... Not only is the movie long, boring and dragging... it also feels like a complete fairytale nonsense! DON'T waste your time, watch DESCENT instead or something! 3/10

Pretty good movie, but creepy being down in those caves. Did not exactly understand the ending, does it mean there will be a part 2?

unique movie very interesting good ideas solid acting

Not a bad movie at all. A good sci-fi/horror/thriller. If you're looking for a monster-in-a-cave movie, well then this is a must see. I thought the special effects were very good, and I especially enjoyed the underwater filming. I've heard some people complain about the acting and dialogue/script in this movie, and I'm not sure exactly wtf these people were expecting, its a monsters-in-a-cave movie people, get a grip. I actually enjoyed the cast. And yes, the dialogue and acting was a bit cliche/campy, but I thought that it was fitting for this type of flick. Good movie, I recommend a watch. 7.5/10

Was an okay watch. Reminded me of 'The Descent'. Had an intresting endind. 3/5

Good stuff, always good to see Cole Hauser adding intensity to character relations. 4/5.

I tried to edit to change my comment, but was able to. I wasn't referring to this movie being boring by far! i was referring to Exorcist II: The Heretic. This movie here is very creepy and suspenseful! Sorry for the mislead. ;)

Good movie! Creepy and suspensful. Watch it!

Nt the best of the creature feature o survival horror genre bt nice 4 one time watch. I expected it 2 b more tense n fast pace bt it had no scares,little character development n was boring at places. I also wanted 2 feel claustrophobic like i felt 4 The Descent bt i didn't. The best scene was the 1 wit Piper Perabo hanging on a rope. Tat was tense. Climax was good 2.

This movie is okay if you like alien cave creatures. Don't know why they thought they had to end it like they did though 4/5
