YMMV / The Simpsons S30 E4 "Treehouse of Horror XXIX"

• Awesome Moments: It's Played for Laughs in the opening, but there's something genuinely awesome about Homer defeating the otherwise almighty Cthulhu in an eating contest (of all things).
• Critical Dissonance: Critics were very dismissive of the episode, overall ranking it as So Okay, It's Average and a clear example of the series' infamous Seasonal Rot. Audiences, however, have been considerably more positive, with this episode having even been the highest rated for Fox on the night of its initial airing.
• Crosses the Line Twice: The Black Comedy really comes to play in "Geriatric Park". There are recycling bins for severed heads. The promotional video has a backdrop of transformed dinosaurs devouring patrons. And Skinner's mutated mother bites off his arm, only to scornfully insult his flavor.
  Skinner: Half of that taste is you. (Agnes bites his other arm off)
• Heartwarming Moments: Lisa calming down the Indominus Rex version of Grampa Simpson by simply staying to listen to his rambling stories (which is all he ever wanted in the first place).
• Nightmare Fuel:
  • It's rather unnerving to see Lisa utterly lose it in "Multiplisa-ty".
  • Many of the pod creatures' designs are quite grotesque and induce plenty of Body Horror. Props go out to the pod that captures Comic Book Guy and the plant that digests Chief Wiggum.
  • Groundskeeper Willie beheading an uninfected Chalmers with a pair of garden shears out of sheer paranoia is disturbing in and of itself.
• Older Than They Think:
  • An Invasion of the Body Snatchers parody previously appeared in the Simpsons comics.
  • Jurassic Park had previously been partial parody inspiration for Season Six's "Itchy and Scratchy Land", in tandem with Michael Crichton's second-most famous work Westworld.
  • Naked Gun 33⅓: The Final Insult did a parody of Jurassic Park about the premise of a theme park with giant elderly people for the Oscars scene in 1994.
• She Really Can Act: Yeardley Smith in the second segment is utterly terrifying in portraying Lisa when her character has a psychotic break and develops multiple personalities, managing to make each different personality unique and memorable while constrained by less than seven minutes of animation.
