I caught this on ABC-TV tonight as I was flicking the channels.  Every year at this time this airs.  I've seen it countless times over the years.  What else can be said?  It's a classic Christmas tale that's in awesome stop motion animation.  It's funny - this Christmas special with its stop motion animation looks better, more authentic, and more believable than the current computer animated Christmas specials, which look like cartoonish video games.  Anyway, everything about Santa Claus Is Comin' To Town is perfect.  I like the fact that it's sort of a "prequel" of sorts, telling the story of how Santa Claus evolved.  The villains in this are so cool and I like the castle, the dungeon, and the overall atmosphere of this Christmas classic.
