Spinal Fluid Seemed to Be at a Premium
14 March 2006 | by (United States) – See all my reviews

If it weren't for the presence of Boris Karloff, this would be pretty bad. Apparently there has been a bout with polio in the community (paralysis) and there is a pretty young victim who the doctor fancies as looking like his late daughter. He makes it his life work to cure her. Unfortunately, he needs the bodily fluids of others to bring about that cure. Of course, he chooses the base, the outcast, for his work because the young pretty girl has more worth in the society than these others. He chooses his victims by judging this worth. He kills them by dressing in the skin of an ape that he killed and skinned. If this sounds silly, it's hard to defend. There's also a subplot of the jealousy of a young man who loves the young woman but may feel if she recovers she will reject him. Karloff's doctor is the constant victim of the community. They don't know what he's doing in that house and so he is victimized by the local kids (your garden variety brats), and looked on with suspicion. He is such a kindly man, it seems odd that there is such venom when it comes to him. Anyway, it's a small town and people do need their preoccupations. It just seems that a doctor with this much imagination could be a little more creative in his methods than the one he chooses. Imagine how lacking in dexterity if you were about 60 years old, running around in an ape pelt. It's rather forgettable and predictable, but it's fun to see Karloff's character.
