I finally just got around to watching this, and I have a couple things on my mind...
First of all, why oh why would you have another baby, knowing that to do so puts them in danger, as well as the rest of your family?
The girl was a liability the whole time. By my count, she:
- got her littlest brother killed
- almost got her other brother killed at least twice
- left her pregnant and due mother alone, during which she almost got killed
- made choices that led to her father getting killed
- got a raccoon killed
Cool concept, annoying characters. Where was all the sand coming from? Won't watch again.
Huh ... I rather enjoyed the film.
I think for me, what seemed like irrational survival decisions to you were the obvious things people would do because they want to live a life as much as possible. Think of lockdown during the pandemic and how much people just wanted to "get back to normal". I think people doing risky things at least some of the time while thinking that it will be totally fine is actually a very realistic take on a post-apocalyptic survival story especially with its timeline being a long one as is the case in A Quiet Place.
Convincing yourself that you can totally get away with something is a way of convincing yourself that things are actually OK, even they are not at all.
or literally think of right now, also during the pandemic, where people continue to pretend everything is just peachy.
