Bird Box, except the invisible monsters are all canine "demons" who fill their victims with the urge to derp, drool, and bark uncontrollably.

First you hear panting all around you, and then your whole world is just MOIST, and you hear ethereal voices around you saying "sit" and "fetch."

You don't really have to worry too much about keeping survivors at bay, though, because a sharp glare and a "NO!" is enough to get them to stop trying to convert you. Also, the demons can be driven miles away just by staring excitedly at the horizon and asking aloud: "Cookie?"

Civilization still collapses. It's just nicer.

Seriously. I've ranted about this before in the context of the film "1408." How come all the incomprehensible extradimensional phenomena are always weirdly hostile to humans? How come the side effects of an encounter with the inexplicable are always not just unpleasant, but *personal* somehow?

In fact, never mind horror. That was half the point of the Saturnians: humans are so full of nicely exploitable pleasure centers that hook right into their behavioral routines. And humans tend to _resent_ pain, so torturing them into doing your will is just asking some Buffy or Jamie Lee type to come fuck your shit up.

No, extradimensional reavers. Learn the wisdom of Rock and Rule's "villain" Mok. Break out the Edison spheres, turn the Final Girl into a useful musical instrument, and make your prey happy, goofy, and useless.
