I think "It's a Wonderful Life" and "A Christmas Story" get way too much airtime at this time of year. I was sick of those two movies years ago.

The ones I like are
"The Bishop's Wife" with Loretta Young and Cary Grant
"National Lampoon's Christmas Vacation" (I think I've reached the saturation point on it, too)
"White Christmas" with Bing Crosby, Danny Kaye and Rosemary Clooney
"Home Alone"
