I watched this while eating Chinese food with my aunt like a decade ago after babysitting my cousin. An absolute blast, takes itself exactly and only as seriously as it needs to.
Honorable mentions: Black Christmas (original only!!); and while not explicitly Christmas movies, I strongly associate Legends of The Guardians: Owls of Ga'Hool (Zak Snyder owl movie), Happy Feet (??) and Rush Hour 2 (?!?) with the day
