YMMV / Apollo 18

  • Big-Lipped Alligator Moment: When Anderson and Walker are driving to the Soviet LK and Walker crashes the rover, the footage slows down to show several boulders turning into larger versions of the alien spiders. This is never commented on, and the large spiders are never seen again.
  • Nightmare Retardant: The movie's kinda creepy until you realize that the monsters are rocks.
  • Paranoia Fuel: The movie ends with a note on how many moon rocks were given to foreign diplomats as gifts, and are now either stolen or missing. And since we know that any moon rock could be one of the alien parasites...
  • Special Effects Failure: The lunar landscape, landing module and suits all look fairly good... right up until the astronauts start moving, at which point it is very, very obvious they're on a soundstage. Seriously, The Adventures of Pluto Nash put more effort into simulating the effects of lower gravity on-screen.
