YMMV / Sometimes They Come Back

• Complete Monster:
  • Original film: Richard Lawson was the leader of a gang of greasers that murdered a young boy and attempted to kill his little brother before dying in a freak accident. With his restless ghost murdering a student to come back, Lawson tortures and kills others to revive his other gang members. Tormenting the now-grown boy, Jim, Lawson attempts to kill his wife and young son, all out of a sense of gruesome unfinished business.
  • Sometimes They Come Back...Again: Satanic teenager Tony Reno was once dating Jon Porter's sister, but murdered her in a ritual to gain demonic power. Killed by Jon with his two subordinates right after, Tony later uses his powers to murder Jon's mother to revive himself from beyond the grave decades later and begins tormenting Jon to get to his teenage daughter, killing all of her friends and acquaintances to revive his minions and finish the ritual by attempting to sacrifice Jon's daughter and achieve the ultimate power he wants so badly.
  • Sometimes They Come Back...for More: Dr. Karl Schilling is an evil Satanist who turned over his own humanity to infernal forces and engineered the death of all but two people in his Antarctic research base. Schilling brings back his victims as disturbed zombies and uses them to kill more in a plot to bring Satan himself to Earth.
• Squick: The story doesn't spare much detail when it comes to describing Wayne being stabbed (including in the genitals) and Jim cutting and biting off his own fingers.
