Plain stupid and totally illogical!

Rating: 4/10 (14 February 2019)

SPOILERS!
A family try to survive by staying quite in a post-apocalyptic world, where almost everybody is killed by blind, super-hearing creatures that look like a child of Venom and the Alien. So far so good. After nearly an hour of hiding we found out that:
1.waterfall sound is enough to hide you
2. Bed mattress over a basement door is totally sound proof
3. Newborn babies don't cry - EVER!
4. Shotgun is enough to kill the creature...
5. apparently the super sensitive hearing of the beasts is vulnerable to high frequency sounds.... (how surprising)
6. The creature is easily distracted and lured by sound- any sound!
So, the conclusions:
1. All the humanity never came with the idea to use soundproof hideouts
2. The most powerful army in the world, equipped with tanks that can survive nuclear blast and jet fighters fester then sound equipped with thousands of destructive technologies- all types and ways against anything, can't destroy invading force of stupid primal creatures, that are soft enough to be killed with shotgun and Stupid enough to be made to run after an alarm clock....
3. Not a single army in the world tried all the sound frequencies against this highly sensitive beasts...
The movie is so logical that is insulting. \the makers didn't even have the courtesy to tell us more about those invaders - who are they, where they come from etc. For 1h and 30min the movie jumped over sounds, zoomed on big scared eyes, and even Emily Blunt dramatic performance couldn't save you of total boredom.
Visually the movie is a cliche - CGI generated creature, straight from PS4 game, thousands of red lights everywhere... because resources are not an issue after the apocalypses. And of curse the corn farm and corn field... how the movie can go without them?!
I can't understand only 2 things - how they cast Blunt, and why this nonsense have rating of 7,5 ?!?
Conclusion - watch only the trailer and save 2 hours of your life!!!
