After a spell goes awry, Aunt Zelda & Sabrina are forced to reenact A Quiet Place with an 80s B movie creature feature budget, comparatively speaking.

The 1st half was pretty good, but there are some serious plot holes.

How exactly would carnivorous bats survive underground for millions of years?

The writers also seriously expect us to believe that people would be starting crazy murder cults after just a few days? I cringed when the priest said "she is fertile".

How is the power still on? Aren't power plants loud?

It also seems completely implausible that this would be a completely world ending event. Can't you just blast loud sirens in the cities which would prevent the bats from homing in on small noises? It's also not like the bats can get through concrete.

There is no logic reasoning in the storyline. I can't see anyone choosing to leave under those circumstances by car and on top of it leaving without a plan! Maybe staying home where there is water and food and where you can choose to not make noise would make more sense. If they would have left to get supplies for boarding the house or stock up on food, okay I get it. But nooooo let's get in the car and drive somewhere without a plan ughhh...
