When hardened psychiatrist "Martin" (Jordan Belfi) arrives at the prison, he is charged by the warden (Tom Ohmer) with certifying that a prisoner is mentally fit. Mentally fit to be electrocuted, that is! Opposite him, shackled to the table is a man (Sean Patrick Flanery) who proves extremely problematic for the normally ordered and structured analyst. That's not least because he claims to be possessed by the eponymous demon and that he has made enough use of this body and so wants to be killed so he can move on! Preposterous we all think, but this orange-suited man knows things he shouldn't, and soon his comments are unsettling and discombobulating "Martin". Now the performance from Flanery is actually quite good here. There is something almost compellingly maniacal about his delivery. The dialogue - well that's another matter. It could be considered thought-provoking or it could be considered banal. You certainly can't ignore it, or the curiously extreme and frequently contradictory doctrines being espoused and countered during what passes for their frankly rather contrived debates. If that's it's purpose, then it's worth a watch. As any sort of light-horror concept, though, it's derivative and unremarkable and it misses the target.
