It came and went with little fanfare. As far as I'm aware, the release was limited. I did get to see it. In spite of all the great buzz from FANGORIA magazine that made me excited to see it, I didn't like it at all. It was neither scary nor interesting. By the time the story resolved I couldn't care less.
One of the best Horror films I've seen in a long while. It's a shame that it didn't have a wider release as a horror film that relies on atmosphere and doesn't revolve around a bunch of vapid teenagers is a real rarity today.
Its distributor, USA Films, has the worst track record in the business for releasing small "under the radar" films-- both this and the equally underrated "Series 7: The Contenders" barely got any release despite great press and buzz.
It played briefly here in Philly, but I missed it and am eagerly anticipating the DVD release! I've heard both good and bad about Session 9, but I think it looks pretty creepy.
