Never was a big fan of the underground/descent style movies. This one was pretty good. I think the creepiest movies are the ones that draw upon natural fears. Claustrophobia is one of mine and the thought of being underground when freaky stuff happens, and the possibility of running out of light and/or oxygen makes for a tense movie. To the people that poo-poo on the "inspired by actual events": That is way different than "Based on a true story". There have been plenty of cave-ins and plenty of miners dead and some where miners survive. So who knows which one "inspired" the writers of this film. Chill out and enjoy a good movie.
