I get comparisons to THE CAVE & DESCENT because they are remote setting rare gems with an all out fight to the death. This movie doesn't have anywhere near their budgets but it is a b-movie that's very well done. If you are a real horror lover, then you know this genre is guilty of some of the worst made crap at times. This film has good action scenes, excellent creature makeup, good acting, and a claustrophobic locale. This is why we wade through the crap. Because we live for these kinds of rare gems.
