Some might see the fact that a book relies somewhat on the readers ability to imagine the scenarios that are being written about as a flaw. Film is often seen as having an advantage in that it is able to portray visually what is happening without the limitations of certain peoples imagination. “The Blair Witch Project” relies on the human imagination much as a book does, and the fact that a lot of the movie involves what you can’t actually see — and often can’t hear — makes it an unbelievably effective horror film. It preys on our fear of the unknown, and does so throughout until the final gut wrenching moments of the film. The found footage horror genre truly began here, where the method was used to the greatest effect.
