#4. SESSION 9 (2001)
Brad Anderson’s “Session 9″ is a little-known indie horror movie with enough atmosphere and creepy vibe for three or four movies. The film centers around a group of friends who are also employees at an asbestos cleaning company, and their current job is cleaning up an old, dilapidated mental hospital — the perfect setting for a horror movie. While “Session 9″ undoubtedly oozes horror from every celluloid pore, there is more than meets the eye, and the ghosts are more human than we thought. If you have never seen “Session 9″, and want an atmospheric little film to make your Halloween night a little uneasy, give it a shot.
