It isn't hard to see why this movie offended so many people. I mean, it's a slasher movie about CHRISTMAS, and it actually has SANTA as the killer. However, I feel the movie deals with an interesting question. What if you suffered some traumatic event right at Christmas, and the event was somehow bound up with one of the major icons of the holiday? This is what happens to 5-year-old William, who, on Christmas Eve, sees his mother raped and both parents murdered by a street thug dressed as Santa Claus -- right after his semi-senile grandfather tells him that Santa Clause punishes those who are naughty. I think the first part of this movie does an effective job of showing the preadolescent William's struggle to deal with this event as he is raised in a Catholic orphanage and brought face to face with Christmas every year.
I was particularly impressed with the portrayal of the Mother Superior. Although she was most definitely from the Old School of discipline, beating children, locking them in closets for extended periods, and such, I somehow was able to believe she was sincerely trying to do the right thing and cared about the children -- that she was not simply a sadistic hag. There was also an interesting conflict between her and a younger nun, who believed in gentler, more progressive methods.
Alas, the whole thing turns rather formulaic when William puts on the Santa suit and goes on his killing spree. So, as a serious exploration of the question we started with, it falls very short of what it could be. As a slasher movie, though, it's definitely above average.
