YMMV / Cornered!

  • Complete Monster: Morty, the seemingly affable deliveryman, turns out to really be the Convenience Store Killer, a Serial Killer who breaks into shops after hours and torture-murders everyone still inside them, stealing the security tapes afterward so he can use them to relive his crimes. When the film's protagonists unknowingly discuss how they would deal with the killer right in front of him, an annoyed Morty decides to target them next, slaughtering each of them using the same methods that they had bragged about using against him; eye gouging, stabbing, sawing, and decapitation, plus a "bonus" bisection for the vagrant who happened to live behind the store. Before finishing off the shop's last employee, who he force feeds donuts, Morty reveals that he is motivated by simple contempt and disgust for his victims, who had to pretend to be friends with and listen to day in and day out as they lived and "whined" about their pathetic, irrelevant lives.
  • Narm: "I've got pepper spray, and I'm not afraid to use it!"
  • Narm Charm: The cornettos in the eyes.
  • Narrowed It Down to the Guy I Recognize: Yeah, it's not hard to guess who the villain is.
  • Paranoia Fuel: As if the night shift wasn't bad enough.
  • Squick: The less than sanitary condition of some of the store's merchandise, Jimmy crushing cockroaches, and Jacko's dog eating his remains.
  • Special Effects Failure: Mostly avoided with the cockroaches, the exception being the fridge scene.
