It's the Griswolds meets Gremlins with a touch of Labrythn and Terror Vision thrown in. That dark counterpoint to Saint Nic is coming to the homes of disbelieving cxhildren, but thism one's not just going to eat the naughty child but the whole stinkin' neighborhood. Humor, practical effects, and a rather enjoyable romp, though if you think it might have a happy chriustmassy ending then you haven't been paying attention.
