Good acting can't compensate for nonsensical writing

Rating: 2/10 (20 April 2018)

Decent acting but absolutely terrible and nonsensical script.
This movie is lauded as something intelligent, above your average horror crap with cheap jump scares and gore. Well guess what, there's not much gore here indeed but enough jump scares and zero intelligence.
When the monster (suspiciously looking much like the creature from Stranger Things) was killed by a simple gunshot to its head, I literally laughed out loud in the theatre. It was like the writer slapped me in the face for patiently sitting through this crap for 1.5 hours and thinking that yeah... these creatures must be completely indestructible if they managed to bring on such apocalypse. But no, apparently no one has tried to use the magic secret weapon - the mighty shotgun.
There are SO many ways to destroy creatures that are completely blind, have no sense of smell and are incredibly dumb to boot. But here, we are supposed to believe that humans are even dumber.
Apart from that, there are innumerable logical inconsistencies and things that don't make sense. A nail that's sticking the sharp end UP from the step, why? What genius built this staircase? The mum waiting for her due date in the house instead of camping out at the river? The family leaving a small child behind unsupervised, in a lethally dangerous situation. Who would do that? Then, as an experiment perhaps, they decide to have another.
The corn field - how did they silently plant all the corn, how are they going to harvest it?
Soundproofing a basement with a mattress, really? If the room is soundproofed enough that you can talk in it, why can't you make a little bit more effort (like pad the ceiling and walls with thick blankets or something), so that your newborn won't have to be confined to a little coffin with an oxygen mask.
The monsters can hear from miles away when you talk inside the house but can't when you breath heavily next to them. Only one is attracted to fireworks but the whole pack runs in the direction of a single gunshot.
They are completely blind and show up anywhere in 10 seconds but are unable to use echolocation - otherwise why can't they sense you moving next to them? Etc etc etc
Some reviewers say nothing in this film should be taken literally, it is some obscure metaphor. I am sorry to say, that was too much obscure. If there was any message in this, it was lost in all the absurdity.
