YMMV: National Lampoon's Christmas Vacation

  • Crosses the Line Twice: The cat scene. The director had to beg the producers to keep it in the film and they relented when test audiences gave it the biggest laugh.
  • Dude, Not Funny!: Many people turned off the movie after the cat scene.
  • Ear Worm: Mele Kalikimaka...
  • Ensemble Darkhorse: Cousin Eddie, who is often considered to be the funniest character in the film.
  • Memetic Mutation:
    • "Merry Christmas! Shitter was full!"
    • Thanks to the movie any house that has a large number of Christmas lights will invariably be known as a Griswold House.
    • "Hallelujah! Holy Shit! Where's the Tylenol?"
    • "Bend over and I'll show you!"
  • Moe: Ruby Sue
  • Retroactive Recognition:
    • It's pretty weird to think that not many people knew who Julia Louis-Dreyfus was when the film came out.
    • Johnny Galecki counts as well, he's arguably more famous now due to his other roles.
  • Sequelitis: The direct to TV sequel is a far cry from the original.
  • Surprisingly Improved Sequel: Held by fans as a marked improvement over the mostly dull European Vacation, and a more worthy follow-up to —if not even better than— the original Vacation.
  • Vindicated by History: Although the film was well-received when it was released, in the years since its popularity has grown. It's now considered a classic Christmas film similar to A Christmas Story and many families have made watching it an annual holiday tradition.
