How bad is it? In a year of bad Xmas films, it's the worst.
Should you see it? Only if you watch cat videos daily. Those people rate this highly.
Tommy and his mother have been caring for newborn kittens, but can't afford to keep them. Hoping that Santa will give them good homes, he leaves them in a box for him, but Santa's allergic to cats! He falls from the sleigh and three kittens must now deliver all the presents themselves. Guess what - Tommy was so good that Santa had planned to give him a kitten as a present (just ignore the "can't afford it" point) and had one in the sleigh, despite his allergy. This was made by the director of "The Coed and the Zombie Stoner," so you know he has a way with children's films.
