A fun and quirky project by Adam Green. Found footage meets mockumentary, with Green and his team playing themselves. Add some horror legends, a madman who may or may not be telling the truth and some freakish monsters and you have all the ingredients for a fun horror flick.
Green decides to shoot a documentary on William Dekker, a fan who wrote him about an underground world inhabited by freaks and monsters. Dekker says he knows the entrance to this realm and is willing to let Green tag along, but when not everything about Dekker checks out, things take a turn for the worse.
Green playing himself really was a smart move, casting Ray Wise opposite of him is also a stroke of genius. Green pokes some fun at himself and the found footage hype, but stays a little too true to the genre, which results in a somewhat tedious middle part. It picks up near the end again though, so fans of Green and/or horror films needn't worry. A neat twist on a formulaic film.
