I'm no fan of Christmas movies, but off the top of my head, in no particular order

1. White Christmas (overrated honestly, but better)
2. Let it Snow
3. Miracle of 34th Street
4. Christmas Vacation
5. Nightmare Before Christmas
6. The Santa Clause
7. It's a Wonderful Life
8. How the Grinch Stole Christmas
9. Elf
10. Muppets Christmas Carol
11. Patrick Stewart's Christmas Carol
12. Home Alone
13. Charlie Brown Christmas
14. Rudolf the Red-nosed Reindeer

And I'm sure I could think of another dozen, if I cared more
