Violent horror, suspense thriller, with a mix of phobia.

Rating: 9/10 (8 September 2006)

I didn't see this movie from the very beginning, but as soon as I realized most of it would take place in such tight enclosed spaces I fell in love. I feel like were lacking in realistic subterranean claustrophobia horror/action films. I wasn't extremely frightened throughout this film, but the combination of action and throwing some very horrifying scenes at the audience really helped me enjoy the movie the whole way through. Not to mention the primal survival fight scenes they mix in.
What really sold me with this movie were the scenes where the only thing visible was what was illuminated by the yellow glow of the flashlights, and around it was a border of empty abyss. I felt like I was inside the caves with the characters. The film throws some very interesting twists at you which I will not spoil for those of you who haven't seen it.
My only critical thing to say about this movie is the ending scene. It was very anti-climatic, and took way to long. But don't fret, the movie will make up for it.
This is not only a great violent horror, it is also a suspense thriller, with a mix of phobia. Go rent it.
