Well, these sequels sure as hell don't get any better. For the fourth instalment of this overly long series, a reporter, Kim (Neith Hunter) is investigating a bizarre suicide, in which a woman threw herself off a building and then spontaneously combusted after hitting the pavement.
Interviewing the owner of the building, a lady named Fima (played by former Bond girl Maud Adams), which happens to be a bookstore, they quickly become friends. But it seems the she is harbouring a dark secret.
It turns out that she and her friends are witches of some sort, who proceed to drug Kim and start doing these weird rituals over her with these bizarre giant insect creatures that appear to live in the ventilation system of the building, or something?
Not quite sure what these strange bugs are about or why they wanted to initiate her into their group, but the story really has nothing at all to do with the previous films. There's no killer Santa and the fact that it takes place at Xmas time has no bearing on the plot whatsoever. Like this element was shoehorned into the script so they could pass this off as a sequel.
Indeed, in the UK it was originally released under the more appropriate title "Bugs", but even so its not a very good.
B-movie actor Clint Howard (Ron's less successful brother) co-stars, along with horror B-movie actor Reggie Bannister, who has a minor role as Kim's boss and this whole mess was directed, surprisingly, by Brian Yuzna (of "Re-Animator" fame), which has to go down as ranking amongst one of his worst films ever
As with the other sequels in this series, this film is best avoided.
