I like all of these already mentioned (kinda hard to really dislike a Christmas movie, though, I reckon; with the possible exception of
Home Alone, that is

). I'm a big fan of
The Bells Of St. Mary's - which isn't
exactly a 'Christmas' film but is close enough for me. And they always double play it with another fave
Going My Way which gets me in a good mood no matter when.
I tend to avoid "modern" Holiday films because they're typically unoriginal but I watched a really good one today. A surprising gem, I thought, called
Karroll's Christmas (2004). It seemed liked a rip-off of Dickens until Jacob Marley showed up and was a corn-rowed ancestor of Jacob's AND Bob's! Note: our esteemed Eraserhead beat them to that joke two years ago - but it was still funny this time around. The Ghost Of Christmas Past? A deceased stand up comedian from the Borscht Belt (I'll leave it to the imagination how he described what he escaped from in Hell - suffice it to say he was partnered there with the Turkish prison guard from the movie
Midnight Express...yikes). The Ghost Of Christmas Yet To Come was a generally grumpy Mini-Me (app. 2 foot tall) sort who was not having a good day. You see, it seems these ghosts made a bit of a Dickensian "oops". They got the wrong address that eventful Christmas Eve and were inadvertantly sent to the home of a Yuletide phobic greeting card poet. Oh, one whose girlfriend had publicly rejected his marriage proposal on a hockey rink on Dec. 24 two years prior. Poor guy --- there was a skating donkey there and she dumped him for the fellow portraying the -um- "horse's behind"! It was clever, smart, hysterical and a wildly unexpected tale. And, thank goodness, all worked out happily in the end. Rear? Something or other...
