So hard, I love different ones for different reasons.
Meet Me in St.Louis has become a holiday tradition.
Miracle on 34th St. is always a Thanksgiving day must, to kick off the season.
Home Alone / Christmas Vacation / The Christmas Story ... all during christimas day when I promise myself not to get out of my PJ's all day!! ha ha ha.......
probably my guilty pleasure is a Hallmark movie I look forward to every year called "The Most Wonderful Time of the Year" with Henry Winkler bringing home an Airport Travler to spend with his neice for the holiday, that one just gets me every time.
