The wife and I have loved 'A Christmas Story' ever since it was first aired. We also love 'It's a Wonderful Life' and a more recent one. 'Christmas with the Kranks'.
ONe day Bad Santa will rollover for 24 hours in a row also I believe/hope. Thats my favorite Christmas movie.
I remember when my brother and I were watching it probably close to 30 years ago, My dad overheard the part where he said "fuuuuuuuudddddgggggeeee,.....only I didn't say fudge". My father found that moment way inappropriate and made us change the channel. Joke was on him, it reaired a little while later.
The really old one from the 50s (I think) is difficult to watch just due to the quality, as it seems they over act and every line is "100% passionate"...some of the newer versions are pretty good, imo.
