I don't really like Christmas movies, probably because they are almost exclusively comedies and I don't really like comedies. I love dramas, action movies, sci fi. But a few are at least watchable:
-Elf. This one was actually quite good but I've seen it too many times it's gotten stale.
-How the grinch stole christmas, any version, original cartoon, jim carrey one or the next CGI one. All decent.
-The Santa Claus cus Tim Allen is awesome
-Bad Santa, adult level comedy
-Home Alone. Good movie, rewatched it with my kids and they loved it.
But Christmas movies would not be my goto. I'd rather sit down and watch something long that you don't usually get a chance to like Godfather movies or Lord of the Rings trilogy or a Star Wars marathon or something.
