I absolutely love the old clay animation Rudolph as well! It was one of my favorites growing up and still is one of my top picks for favorite Christmas movies.
I really love the cheesy, predictable movies on the run-up to Christmas. There’s one on Netflix called something along the lines of “The Holiday Calendar” which is quite good!
But as it gets closer to Christmas, I love watching the classic movies like Elf, Home Alone etc! And recently joined in with my parents tradition of watching “It’s a Wonderful Life” on Christmas Eve.
I love the classic ones, like "Year Without a Santa Claus" "Santa Claus is' Comin to Town" "Rudolph the Red Nosed Reindeer."
I also love "Polar Express" as that movie was a big part of my childhood.
