I struggle with this concept. perhaps Im not open to new traditions- but in a world of commercialism, I guess I dont like the message this portrays-- "be good because Santa is aatching through the elf, or you wont get presents". that is how I perceive it- we are all entitled to opinions.
I am also Christian so i may take a different approach(so not to kill that magic of Christmas- elf mysteriously moving in the night)- i may set up the nativity scene and have that move in the night. and focus on doing acts of kindness every day

Elf is too creepy.. I think We'll stick to an advent calendar :)
