Dwayne Johnson's Red One wasn't a masterpiece of cinema or anything but I really enjoyed it, I especially liked the additions and spins it took on Santa mythology.
-Santa, every year a couple days before christmas, will hide in plain sight as a Mall Santa so he can remain in touch with the kids he delivers gifts for(this one's my absolute favorite, it's such a natural idea)
-Santa can look into the souls of adults and is capable of seeing them as the child they once were.
-Santa will sometimes have his reindeer and sleigh parked in a military aircraft hanger(that's just a funny visual come on)
-While the North Pole workshop is a big elaborate christmas themed futuristic city now, Santa's original more quaint wooden workshop is kept at the center in a display
-Santa literally shrinks and grows to get through chimneys and even has his presents shrunken when delivering them and grows them when placing them in houses.(derivative of antman but still pretty neat)
-Toy Store backroom closets are portals that serve as gateways to both the north pole and other toy stores throughout the world.
-This movie does the "Krampus is Santa's brother" thing but has it be that the Naughty List was a creation HE made, and to prevent him from doing anymore bad Santa stole it from him
