"Possessed by the Devil" gets 5 stars and then some. This was a fantastic episode which was also rather scary. Listening to it was more terrifying than the ridiculous horror movies that are out today. I am realizing that when Mystery Theater did stories on possession or devil worship, they went the whole way. Ian Martin is a great writer, but his voice is so distinguishable--in this episode he played an arrogant veteran doctor which was perfect for him. Leon Janney was the possessed brother. Janney did dozens of Mystery Theater episodes and he was fantastic as a possessed, love-sick student who had sibling rivalry issues. If you get the chance, listen to this horrific episode.
