Very few movies are made this way, the sheer rawness of this movie makes it all worth viewing, even though it keeps the same set the whole movie, it keeps you suspended, this is basically the closest thing you will get to the feeling of being buried alive and the movie really grows on you if you understand it.

It's one of the few movies that shows you how cruel, stupid and ignorant some people can be, in my opinion this is something that very few movies is able to capture.

Its raw and has no mercy, one of the most brilliant films i've seen and the acting is awesome, if you like suspension and an awesome thriller you won't be disappointed, a true pearl.
