A simple tale of a group of youths getting lost in a dark dingy cave has a lot more to offer than you expected.
First of all, there are no ghosts. But what has been shown to be as monsters are humans themselves. It is debatable. How do you survive with no food and water nearby? Do you just keep searching searching searching until you pass out or is there an even more devilish way out? This film showcases exactly that.
I am from India and first things first, I find it absolutely hilarious or actually weird to see men and women happily show there naked but*h*les on the camera (one of them actually, on a serious note, goes on to show his naked but*h*le in the camera). Seems, Spanish censor board allows such things. In India, censor board members would have simply passed out not by seeing the main part of the film, but by seeing those naked as*es and bu*th*les .
Next thing is the main part, the cave. It's shot really well. I truly felt tensed and scared as the lost group tried figuring their way out and things get absolutely terrifying towards the climax but its ending is kinda cold and not well made.
Great entertainment for a night.
