Factual error: When they first get attacked in the mini van, the side windows crack and get scratches. (You can see the "spider webbing"). A side window shatters in small pieces when they crack slightly.
Plot hole: Within only a few days, cults have formed looking for fertile women? Not remotely likely.
Suggested correction: Exactly how is this not remotely likely in a fictitious horror film involving an outbreak situation (and state of emergency) that has never happened before. It's not a plot hole when irrational, terrified, or crazy people do irrational, terrifying, crazy things.
The plot hole is spot on, no way does society break down in total anarchy in just a few days, you're basically saying all law enforcement and military agencies will somehow cease to exist.
Not cease to exist, but certainly have other things to do than investigate a few random cults. Who'd to say they'd even know these cults have formed?
Visible crew/equipment: In the scene at the gas station where the father is explaining to the son how he met his uncle in high school, right as he begins explaining it you see somebody's head dip behind the head of the father, but you don't see it come out the other side. (00:20:42)
