It’s completely crazy... and I really enjoyed myself! I do have to mention that the ending felt pretty weak; I'm not sure what to make of it, but I still found ‘Santa’s Slay’ enjoyable overall. Not every attempt at humor connects, as you might expect, but the intense threat and violence associated with Santa is genuinely good to watch, I have to admit. It does get violent ("only" rated 15 on Prime UK, by the way), so be aware of that if it's not your thing. Bill Goldberg is a fantastic choice for the role of the large man in red; he really embodied the character and looked perfect. The actors supporting him aren’t quite as impressive, although Douglas Smith, Emilie de Ravin, and Robert Culp all do perfectly fine work. I also appreciated the special effects—they're not spectacular, but they function well; there was one scene that didn't quite hit the mark, though I can’t remember which one, so it probably wasn’t too terrible. I did pick up on a couple of instances of questionable ADR work and, as previously stated, the final moments are somewhat disappointing. Nevertheless, everything that comes before more than compensates for those shortcomings, to be honest.
