All variations on, 'The Monkey's Paw'

This movie's storyline has been done before in Hollywood, decades ago. I even remember watching an old, black-and-white movie that depicted a mad scientist bringing back to life a dead man with an experimental serum. Only, the resurrected man wasn't evil, but totally sad and depressed. When he dies for the second and last time, one of the main characters implores him to describe what he had seen the first time he died. The dying man mutters, "...beautiful...and..." then dies before saying another word.

But typically, the Hollywood horror movie plot is a metaphor of sorts of the ancient human practices of the occult, divination, and necromancy. The black arts of resurrecting the dead, namely the recently deceased's soul to converse with it was considered taboo. Raising the dead to become zombies or ghouls was considered obscene in the most horrifying way.

Hence, in the late 20th century and 21st century, these ancient themes worked their way into the recycled horror movie storyline in that resurrecting someone who has died is an unnatural, obscene act. This does not include rescusitation of someone who was drowning or had a heart attack. This is someone who has flatly died for good, no doubt, no questions. So the resurrected is often considered without a soul and subsequently acts in ways that may be from vile to sociopathic, no longer the loving or caring person they may have been previously.

There are interesting variations on this them. THE COLOSSUS of NEW YORK was a avante garde, sci-fi/horror movie hybrid from 1959. It was even in black and white. A world reknown agricultural and bio-engineering scientist who had been working on ways to improve the world's agricultural food crop supply, dies in an unfortunate accident. One of his main colleagues, his own father, refuses to accept his son's death and pressures a reluctant cybernetics engineering expert to build an android to house the dead man's brain. The resurrected dead man's brain almost goes beserk but the father calms him down with reason and appeals to saving humanity. Later on, the android scientist simply dictates his work to the lab scientists because his metal, robotic android body is too stiff and clumsy for delicate lab work. As you might expect, things don't remain stable for long before the robot scientist loses it for good and goes on a rampage.
