Here's a little but of "The Winter of Free" for you.
If you like Mystery Science Theater 3000 and the like, there are a few Christmas movies available for free on TubiTV for you to watch online. MST3K has the classic Santa Claus Conquers the Martians available, as well as the poorly-dubbed Mexican Santa Claus (the one where Santa has creepy robotic reindeer and fights with a proxy for the devil). The RiffTrax guys also revisited both of those films at live shows with new jokes and extra riffs on Christmas shorts. They also riffed a bunch of other obscure Christmas films and shorts. And if you can't get enough of Santa and Martians, Cinematic Titanic (basically all the MST3K people who didn't go to RiffTrax permanently) doing Santa Claus Conquers the Martians as well.
