I always like watching one of the older ‘A Christmas Carol’ movies. The Alastair Sim one is most classic for me. If I have time to actually see a live production, even better.
I also like seeing some of the older TV classics, although I don’t make a point to watch them every year - Frosty, Rudolph and Grinch. And no one mentioned ‘A Charlie Brown Christmas’? Truly classic, as well as the Vince Guaraldi soundtrack.
While van has never seen Die Hard, I have never seen ‘A Christmas Story’ or ‘Elf’ all the way through. They don’t do it for me.
I like ‘Home Alone’ but I find ‘Home Alone 2’ a bit too gratuitous for me.
I also like ‘Meet Me in St. Louis’ and ‘Holiday Inn’ this time of year, although I wouldn’t classify either as strictly Christmas movies, but maybe Christmas adjacent.
