Nightmare Before Christmas, Muppet's Christmas Carol, and Christmas Story in that order. If we got the Beeb's A Child's Christmas in Wales I'd watch it. I never was a big fan of A Wonderful Life, but I do love Miracle on 34th St (but haven't seen it in years). Of the "has some Christmas theme in it but isn't a Christmas movie" I'd have to say Meet Me in St. Louis with Judy Garland.
