You could definitely argue that the story and traditions surrounding Santa are a modern-day folktale so I think it's appropriate to draw your attention to a new featurette (about 25 minutes) now available online from Disney.
It aired on ABC on December 8th but now you can watch it ('with limited commercial interruption') in HD online.Now: I've known about this for a while and the promo posters and artwork I saw didn't interest me at all BUT I finally saw this yesterday and found this short to be very sweet, full of heart, (lots of great and gentle humor that doesn't try to be too clever (most of the time) and doesn't veer TOO much into the 'self-referential' realm, very Christmas-sy (nodding to more Christmas traditions than you may realize we include in our Holiday celebrations) and, overall, possibly one of the best things to come out of Disney features in a decade.So take a look. It's free to view HERE (and I strongly suggest full screen so you can properly enjoy it).
I'm including a preview below, just in case ABC takes it offline (I know they're planning to air it yearly from now on, so in all likelihood it will disappear sometime soon). It doesn't quite give the sweet feeling that the actual short manages to capture but it explains the premise (not necessary to know to enjoy the short by the way). If you just watch this promo/making of and it still doesn't appeal, give the short a go anyway. I was pleasantly surprised. Maybe you will be too. :)
