For anyone who is wondering why the hell this would be on horror blog, I ask consider your own family.  I don't think it matters what religion you are, whether you celebrate Christmas or not or whether you even have a large extended family--holiday celebrations of any sort can be stressful at best.  I quit doing those big family affairs years ago!  Saves a lot of heartache and the odd hand stabbing affair, or at least sneers from down at the other end of the table that tell you junior is not happy to be there and is mad at Mommy & Daddy about it, but they just know it's not their fault....it's YOURS!  Who in the world would even be slightly intimidated by a man in Santa suit holding an ax after that????  Besides there's a Ghostbusters joke in the script!
