I LOVE Home Alone! I haven't seen The Nativity Story. Will add that to my list of movies to see...
Lots of good movies on your list!
I was thinking about Scrooge awhile ago ( it's one of my favorites) and thinking that the point is we are supposed to get out there and help people, be involved and not just think of ourselves...and how somehow we have maybe mistranslated the message to we should all have BIG Christmases, lots of presents and party hard during the holiday season. That Christmas everyday and keeping Christmas well means helping mankind, making the world a better place, being generous and not miserly with our time as well as our worldly goods...however, I had a HARD time in English classes getting the point of a lot of literature and would run off down rabbit trails that no one else, including the teacher, was seeing at all...literary or film analysis isn't one of my strong points.
I will admit, though I love It's a Wonderful Life, it feels too long to me.

When I was a kid the Mr. Magoo Scrooge cartoon used to scare me!
