That's a rhetorical question, by the way. You don't have to answer that, All the Creatures Were Stirring has got you covered.
The first segment - "The Stockings were Hung" is one of those stories where some sort of evil mastermind traps a bunch of people in a room and tries to get them to kill each other. In this case it's a group of office drones at a company Christmas do. It's fun, for a little bit, until the character writing gets so ludicrous it completely breaks any possible immersion - one of those cases where you wonder if the writers ever saw how human beings actually interact, a copy of a copy of a copy of lazy horror tropes with no verisimilitude or grasp of psychology. It's bad, really bad.
"Dash All Away" has a man (Matt Long) lock himself out of his car in a deserted parking lot - deserted except for a van with two slightly cultish-looking girls (Catherine Parker and Mekeda Deklet) whom he needs to engage to call his family and roadside assistance. It's the only short in the movie that manages to build some suspense, as the situation is very relatable and effectively creepy. It also has, when it arrives, a cool monster and a nicely bizarre explanation as to what's going on. High marks.
It's followed by what's almost a throwaway joke, a story where a man runs down a reindeer in a country road to then be followed home by a mysterious assailant that lights everything around it red. It's a hilarious premise, but the next-to-zero production budget means that nothing is shown, completely buggering any chance it had to be a cool (and very funny) creature feature.
What's interesting with this one is that directors Rebekah and David Ian McKendry go full on with the giallo and '70s Italian horror imagery, from the leather gloves that the man dons to manhandle the downed reindeer to some trippy, very cheap-looking photography-based visuals, to some of the editing and even a goblin-esque (on a budget) score. The short ends up being fucking dire, but it's got some interesting visual callbacks in a movie that otherwise looks pretty drab.
What seems like a straightforward lycanthropic (were-reindeer? elapusthropic?) premise fortunately takes a left turn into Twilight Zone territory, complete with an aspect ratio change, (very flat) black and white photography, some overtly familiar musical stings, and sci-fi elements. Despite one major dangling thread, it ends up being a very cute, heartfelt Christmas story and it'd be a really great note to leave things on.
