YMMV / The Power (1968)

• Complete Monster: Adam Hart, aka Arnold Nordlond, born with vast Psychic Powers, considers people his playthings and has abused them since childhood. Taking a new name, Adam destroyed nearly every trace of his old life, brainwashing his hometown’s mechanic to kill anyone who turned up asking about him. A true sadist, Hart enjoys playing with his victims, often inducing mind-breaking hallucinations before inflicting agonizing deaths. When his old friend Professor Henry Hallson discovered the existence of another super genius, Hart became obsessed with removing a potential rival, murdering Henry by imprisoning him in a centrifuge. He then targets Professor Jim Tanner, manipulating events to look like Tanner killed Hallson before almost murdering him through induced agony. Going after Sally Hallson, Hart rewrote her entire personality, leaving permanently damaged and barely able to remember her husband. Stalking Tanner, Hart caused Professor Melnicker to die from a heart attack. To divert suspicion he faked an attack on himself, taking the opportunity to almost crush Tanner with an elevator. Hart then tried to run Tanner over before running him into the river, and set Doctor Van Zandt's house on fire, killing him and his wife. When Tanner finally confronts him, Hart attempted to torture him to death, forcing him to experience sub-zero temperatures, his flesh burning off, the empty vacuum of space stripping him down to the bones and reliving all his friends' and colleagues' deaths, all whilst he cheerfully narrates.
