Unsure if this was meant to be a deliberate so bad it's good B Movie but it's mostly just bad. Awkward dialogue full of cliches. Inconsistent performances with some actors trying hard for a serious tone and some trying to wink at the camera.
Someone clearly wanted to make a serial killer Santa Claus and then added a Mrs Claus in the style of Harley Quinn. It's hard to get the tone right for a B Movie but even harder to do a decent Harley Quinn impression.
Even those with a high tolerance for cheap horror films will find this hard to love. Perhaps save yourself the time watching this and seek out a better Xmas horror like Anna and the Apocalypse or Krampus.
