Wow. That's insanely intense... I'm stunned. There were a few mistakes and typos here and there:

"Why the families why" There should probably be a question mark there. Also, at some point there's a "too" that seems out of place and strange.

Other than that, that was one of the creepiest, more intense, terrifying, incredible scripts I've ever read. Wow. Just... Wow. It's seriously chilling. I don't even know what to say.
