The Polar Express, 
A Christmas Story, and 
The Santa Clause trilogy will always be my favourite Christmas movies. I've only gotten into 
A Christmas Story during the past few years (though it's always been quoted religiously by my parents lol), but I've loved 
The Polar Express and
 The Santa Clause trilogy since I was a kid. I have so many fond memories of watching them growing up; I used to listen to "When Christmas Comes to Town" from 
The Polar Express on repeat. 
The Polar Express' animation style isn't my favourite these days, but like with 
Monster House, I still think its style adds to its charm! My mom and I usually watch it at least once every holiday season (along with 
A Christmas Story), and I'm hoping to watch 
The Santa Clause trilogy this year as well! It's been a while since I've seen the movies in full, and I still haven't watched the series on Disney+ yet! 
I also love 
The Ref, Jim Carrey's 
How the Grinch Stole Christmas (love the 1966 animated version, too!), and 
Ruldoph the Red-Nosed Reindeer (1964)! 
The Nightmare Before Christmas is one of my all-time favourite movies as well, but it's more of a Halloween movie for me.
