Great thread!
I'm old school 'cuz I'm older than dirt, almost.
"Holiday Inn"
"Christmas in Connecticut"
"Miracle on 34th Street"
"White Christmas"
Yes, all the original versions from the 1930s, '40s, and '50s.
And for a modern movie, "A Christmas Story"
All those TV cartoons from the early 1960s - absolutely abominable animation.

I can't stand 'em. Wouldn't even let my kids watch 'em when they were little.
