The Descent (Unrated Widescreen Edition)
This is one of my favorite horror movies of the past few years. I group of good friends rallies behind one of them who's going through a dark time (lost her family in an accident). They decide to go on a cave diving expedition like the use to in the old days. However, this time around they run into something sinister and deadly. The fight for their lives begins. If you're claustrophobic and afraid of the dark, don't watch this movie. Or maybe you should. MAKE SURE YOU GET THE ORIGINAL VERSION! The U.S. version has a different ending. Blah.
