Christmas means a great many things to a great many people. It can be the season for romantic comedies, a beautiful time of togetherness, a capitalist nightmare, a rough time, or it might mean nothing at all. It can also be the perfect time to process any and all of those feelings through the wonderful world of horror.
As with any genre, you have stone-cold, unassailable classics like Gremlins on one end of the spectrum and utter dreck on the other (no need to name names here, but you've probably seen one or two). Since the century flipped from 20th to 21st, there have been a ton of entries in the field of holiday horror, so we're looking at the best of the bunch.
