Ah, you're a family after my own heart. I absolutely love Little Women and The Nun's Story, and very much like Goodbye Mr. Chips, and The Thin Man. Even if Christmas is tangential in them, it's very important, and they're right for the season.
I also dislike Holiday Inn and White Christmas. I think I watched them once. That was enough.
I'm shocked you know My Three Angels. So few people I know have seen it. I do like it very much.
The only film where we part company is Meet Me in St. Louis. I know it's heresy, but I'm not a big Judy Garland person.
Which is your favorite version of Little Women? My own favorite is the one with June Allyson.
Of the ones you haven't mentioned, I'll start with my absolute favorite "real" Christmas movie: It's a Wonderful Life. I've lost count of how many times I've watched it, and I always cry.
A Christmas Carol is also a must. My preferred version is the 1951 one with Alastair Syms.
We do also watch Home Alone for comic relief.
While You Were Sleeping, while not a Christmas movie per se has a lot of Christmas in it, and I really like it.
Some more of my favorites that are like that are:The Preacher's Wife with Cary Grant and Loretta Young, and An Affair to Remember with Cary Grant and Deborah Kerr.The Bells of St. Mary's is usually on there too.
I do watch Miracle on 34th Street every year, but it's not in the top five.
Honorable Mention goes to
Shop Around the Corner
As anyone can see, I don't like anyone messing with Christmas. The more sentiment the better.
Years ago they used to broadcast Amahl and the Night Visitors. I can't find it anymore.
Between being taught by nuns all the way through high school, and movies like The Nun's Story, The Keys of the Kingdom, Heaven Knows, Mr. Allyson, Lilies of the Field, and especially the Song Of Bernadette, I was convinced for a long time I was meant to be a nun.
