Apeshit/YMMV

• Complete Monster: Several examples:
  • The mutants: Weirdly deconstructed. They are a mated pair, and she is pregnant, so they might just be defending their territory.
  • Crystal: She gets off on the idea of late-term abortions, and in her girlhood had acted on those fantasies by swallowing small animals alive and imagining them dying inside her, when she wasn't torturing and killing them outright. At the end she helps Jason sodomize the male mutant (using a butcher knife, because the idea of touching him is icky) and dismember both, tearing the female's fetus from her womb.
  • Jason: He snaps out at the end after he and Crystal trap the female mutant in the basement, and when her mate comes for her he beats the everloving hell out of the male mutant with a bowling ball on a chain, sodomizes him, dismembers both, and is ready to help Crystal dismember the female's fetus.
  • Dan: He liked to torment his sister Stephanie with fire ants and cigarettes, and forced her to have sex with him repeatedly. Not only does he not care when this gets her pregnant, but he plans to make her live as his wife for the rest of their lives.
• Crosses the Line Twice: Stephanie puts a shotgun in her mouth and blows off the back of her head? Tragic. Stephanie is still alive despite missing half her skull and the associated contents? Horrific. On the way to get help the delirious Stephanie starts giving a blowjob to the driver, who realizes that he is actually penetrating the ragged hole in the roof of her mouth? Hilarious.
• Fetish Retardant: Crystal gets turned on by "erotic abortions".
  • Jason gets not one, but two blowjobs from Stephanie after she blows her brains out. He is equally turned off both times.
• Nausea Fuel: On their way to the cabin, the impending victims heroes protagonists find the pulverized, rotting, stinking corpses of a lot of animals in the road. Including a hunter. Who is apparently still alive.
  • Erotic abortions.
  • Desdemona, already disemboweled, gets her intestines shut in the basement door. She must chew them off to escape. The text describes, in lovingly intimate detail, just how horrible that tastes.
  • Everything Crystal and Jason do to the mutants.
• Nightmare Fuel: Many All of the horrific mutilations count as this.
  • And every single thing Crystal and Jason do when they corner the mutants.
