I've known of this little Christmastime occult monster tale for years but never sought it out until now. The only point of interest it had for me was the presence of TV's Grizzly Adams in the person of big, hairy Dan Haggerty. I have some vague memories of the show and of him as a pleasant enough actor with a certain skill set that I just couldn't imagine translating well to a horror film. Turns out I was right.
But I did laugh a LOT at Haggerty's discovery of a bomb planted in his car! That whole scene must be seen to be disbelieved!
