YMMV: Treehouse of Horror

  • Alternate Character Interpretation: in spades. The episodes invoke this in order to trigger the murders in each segment. See Idiot Ball in the main page.
  • Ensemble Darkhorse: Some of the monsters such as Count Burns, Devil Flanders, and King Kong Homer. An unusual example is Krusty in vampire getup from Treehouse of Horror IX who, despite not really playing a role in the segment, has been seen in Treehouse of Horror merchandise and media.
  • Family-Unfriendly Aesop: Ned teaches one to Bart, Lisa, Milhouse and Nelson about the seven deadly sins in Treehouse of Horror XVIII.
  • Hilarious in Hindsight: In one episode, Snowball 2 is brought back to life with occult. In the recent Archie Comics miniseries, Afterlife With Archie, an attempt to bring back Hot Dog starts up the zombie apocalypse.
    • In the Treehouse of Horror X short, 'Life's a Glitch; Then You Die', a virus (in this case, the fabled Y2K Bug) causes chaos around all around the world upon computers, and computer-controlled devices starting from Homer's computer, leading into the apocalypse. Around 10 years later, Summer Wars would also have it's plot kick off by some guy's computer device accidentally triggering a virus, and causing havoc to devices around the world. But the big difference here is that Kenji never unleashed it (he just got one letter off, and by being the first to respond, he was framed), it was Wabisuke's doing, and it doesn't end on the apocalypse.
  • Nightmare Fuel: Some of the shorts are really scary such as Nightmare Cafeteria and There's No Business Like Moe's Business for starters.
    • The Gremlin's first appearance in Treehouse of Horror IV "Nightmare at 5 1/2 Feet" with green fur, a wide Slasher Smile and Wide Eyes and Shrunken Irises.
    • Treehouse of Horror III to Treehouse of Horror X featured several disturbing Couch Gag sequences, including: the Simpsons family appearing as skeletonsnote ; erupting from the ground as zombiesnote ; mismatched Frankenstein-esque monsters note ; open-eyed hanging victims (with Maggie still sucking her pacifier)note ; The Grim Reaper sitting on the couch, and the family members dropping dead one after another (and on each other) as they rush to the couchnote ; the family getting electrocuted to death by an "electric couch"note ; the family actually never making it to the living room due to screwing up the timing of the openingnote ; and a Grand Finale of sorts for the couch gags with a Continuity Cavalcadenote .
  • Screwed by the Network: Fox has been generally unable to schedule these episodes within the week before Halloween since buying the exclusive rights to the World Series in 2001.
    • This was even lampshaded in one special when the episode aired passed the Halloween holiday with Kang and Kodos stating it was near Christmas time.
  • Ugly Cute: The blue Gremlin at first... until the ending.
  • We're Still Relevant, Dammit: The post-Seasonal Rot episodes stopped being scary and are instead just parodies of 'relatively new' movies and TV shows with Family Guy-esque sociopathic humor.
