What was the purpose of this movie?

Rating: 1/10 (21 October 2018)

I don't get it. Without hope of leaving that place..why would you choose to live like that? I would stand in the middle of a field and scream..just to get it over with. The movie could have ended with them driving away with the piercing noice of her cochlear implant keeping the beast away. So aliens took over the planet and this is how you lived?
