Nothing makes sense.
Dad apparently is some brilliant prepper guy, yet makes a system that can only sustain 2 people... aside from him simply adapting the current system, why not build it, so that it can at least support 10 people... just in case.
Instead he kills himself.
Then you have the 2 geniuses that flee what seems to be a far better place to do what exactly?
If the woman could copy the tech, she surely could fix the generator in the better place?
Also it seems there are a lot of people there, not a single one of them has any tech skills?
Seriously I could go on and nitpick on everything for hours, but the big issue is that the story is bad and never pulls you in, so you start seeing the flaws more and more
