National Lampoons Christmas Vacation.
I find most of them pretty awful.
I suppose that "It's a Wonderful Life" is OK, and the Alastair Sim version of "A Christmas Carol" is better than most versions that followed it.
Planes, Trains and Automobiles and Elf.
The Wizard of Oz.
Lions and tigers and bears oh my lions and tigers and bears oh my.
Elf, A Christmas Story and Deck the Halls
"Bad Santa" is the BEST Christmas movie ever made.
I like Elf and Christmas Vacation
All I want for Christmas.
