I have to say, that I think this movie didn't get the just credit it is due. In my opinion it is one of those overlooked treasures in the horror flick genre. Why it didn't get more credit? I don't know. It has a great story, group of characters, and setting. It also relies on "old school" psychological scares rather than "slash and hack" gore to get the same effect. Which is a great feat if you can pull it off, which very few filmmakers can.Session 9 starts out with a cleaning crew that manages to get a contract to remove asbestos from a abandoned mental institution. A rather rushed job, due to the fact in the bid for the contract, they apparently stated they could get it all done in the shortest amount of time. So tensions are already high between team mates. Then add into the factor each of characters personalities and stormy pasts.Things just go from bad to worse after crew member, Mike (Stephen Gevedon), finds a old recorder and tapes from a group of therapy sessions, 9 of them in fact. Therapy sessions for a patient named Mary, who is afflicted with multiple personality disorder. All of which seem harmless except for one named Simon. Simon is the one the other personalities don't, or won't talk about, and seem to dislike and are fearful of.
From a brooding atmosphere, and sounds to, mysterious disappearances, and a unknown lurking presence of something almost evil, this will keep you hooked until the very end. Session 9 is a slow building horror flick that is full of chills and is a great flick in my opinion. Definitely worth a watch!
