YMMV / Slaughter High

  • Darkness-Induced Audience Apathy: The bullies are all unrepentant scumbags that that blame Marty the first chance they get when they get caught and Marty murders innocent people at the mental hospital he's in for no good reason before vowing to take revenge. By the end, the movie leaves you wondering who you're supposed to root for in the first place.
  • Harsher in Hindsight: Marty's mistreatment by his classmates becomes even more disturbing when you realize Simon Scuddamore, the actor who played him, committed suicide shortly after the film's release. Granted, it didn't have anything to do with bullying.
  • Idiot Plot: Because one door was electrified, the cast decide to stay inside the school, despite all the windows they could escape through.
  • Narm: After Marty crashes through a window, the Final Girl throws a spear at him, which misses. She does this so half-heartedly that it's funny.
  • Nausea Fuel: Ted's guts spilling out after he drinks a poisoned can of beer, and Shirley melting in the acid bath.
  • One-Scene Wonder: Coach in the scenes set in past, who has a no-nonsense attitude towards the students' shenanigans.
  • Paranoia Fuel: Ted drinks an innocuous-looking can of beer, which causes his guts to melt.
  • Retroactive Recognition: Billy Hartman, who played Frank, would go on to portray Terry Woods in Emmerdale.
  • Rooting for the Empire: Because they all had a part in pointlessly tormenting Marty, it's hard to care about the main cast.
  • The Un-Twist: Marty being the Killer. Seeing how ridiculously obvious the foreshadowing, the fact he is the only suspect and how he wears a mask for most of the movie, you'd be forgiven to expect a twist by having the killer be someone else. But no, it really is him.
