i go into the hole expect another badly act slasher flick with crazy teen run around subteranean passage way . i come out a different man . this film be a disturbing and cleverly and psychologically frightening film . with a very low blood and sex rating and this film instead shock by how it manipulate the viewer . for example and a the character become more and more dehydrated i start to experience the same symptom a them . clever use of sound and light maybe and but highly effective . i wouldn not recommend anyone to see this film they might think i be mad . but i will say that you will be miss out on something if you do not see this film . provocative and well direct and nicely shot and reasonably script and just about acceptably act . vvg indeed .
