Why would these people be so willing...(Spoilers)
to kill themselves? They was just ordinary people, Redman was a lowlife bigot redneck, the waitress had a kid, you telling me a vision or whatever has them full on dedicated to killing themselves no questions asked if this couple didn't choose to be sacrificed?
That seems like some serious cult level dedication to something they really didn't know anything about. I just didn't buy that cause they had a vision one day they was 100% willing to commit suicide to supposedly prevent them from coming true. Doesn't feel like something you would easily commit to doing and not think for a second what you're doing might not even work.
Especially Redman, he seemed like a huge asshole that wouldn't give a shit or care enough to even entertain the thought of it even if he had some kind of vision.
