Scary and fun, but the ending is anticlimactic. The movie follows a group of urban explorers as they search for the fabled philosopher's stone in the catacombs beneath Paris. The characters are well drawn and the setting is creepy in and of itself, but the movie crumbles under its own weight in the third act. The ending seems slapped together at the last minute, as if the filmmakers didn't quite know what to do after all hell brakes loose. Unfortunately, there is a lot of squandered potential here.The found footage gimmick is wearing thin, and genre fans will recognize many moments stolen from better films (see The Decent and Death Line). 3/5 Stars
