* On a scale of 5 popcorn buckets, "Krampus" pops up 3 buckets of silly, not-your-typical-Christmas fare. You might even want to save some to string on the tree. It includes some scares, some laughs and a reason to shake off the seasonal blahs if you feel them coming on. MPAA rating: PG-13. Running time: 1 hour, 38 minutes.
