John actually doesn't so now I am really ruining things for you, but don't be sore because I'm not going to tell you anything else. However, there are a few more things you need to know about this film. It is based on a horror novel which just came out with a sequel recently. The production value is a little on the bargain basement side, but it is a conceptually clever & trippy plot so you will forget and forgive them for that. This material could only be done credence by a master or it would have been a fine steaming pile. Thankfully, this found its way into Don Coscarelli's hands. The perfect man for the job.
I've said enough. The rest is up to you. Weed isn't required, but would you really be on this site without it.
