While this episode was good I always enjoyed "Tales from the Darkside" better for horror shows. TftC was only really good for the gore and nudity since it was on HBO. TftD I thought always had better stories but they were horribly acted. Anyways, if you want a good Christmas horror story watch the Tales from the Darkside episode "Seasons of Belief" on Youtube here
