How bad is it? Technically one of the worst films made.
Should you see it? No, which is okay, because it's REALLY hard to find a copy.
This was a Super 8mm home movie, apparently shot with the built-in camera microphone and sound edited in hard stereo (i.e., sounds are one speaker or the other. Added music, at improper volume, is all on one side). A young man is being investigated by the police and he tells his story, which is about his uncle and his "Reanimator"-like experiments. Uncle Dr. Strain has low tech facial sores and a penchant for 80's casual wear, as well as a basement full of zombies. He tries to transfer his soul into his nephew, but it goes into a zombie and then there's a chase scene... that stops abruptly without resolution. There's a cemetery that rivals the one in "Plan 9" for shoddiness. Extraneous noise - dogs barking, wind, lawn mower, an argument - drown out the dialogue in places.
