The plot had more holes than Swiss cheese

Rating: 3/10 (11 June 2018)

* The monsters can hear you km apart but can't here you when in the same room as you and a baby is making noises.
* You have never left your daughter to go in your man-hole (the basement). Why?
* Why do you not let her go with you? She seems much more capable than her brother, even though she's deaf. Which leads me to...
* How the heck is she more capable at keeping silent? A deaf person would be terrible at this (anyone with hearing issues, please correct me if wrong :) )
* What happens when you snore?
* When she had the baby and they got in the room below the mattress, the mother says: "It worked". My question: Did you guys not test that before actually using it? Seriously?
* Why not live in that room in the first place and be able to talk?
* Why did you not check where that sack was caught?
* Why not use a loud military siren?
* Why did they sink in the corn like it's quick sand? It does not work like this!
* Why did the monster not sink?
* Why did they not sink when a huge metal plate was on top of them?
* Something I did not notice during the film, but still valid: Why not live under/near/at the waterfall or in a sound studio?
* Why not live in a glass skyscraper?
* I get that, kids especially, can make illogical decisions when under stress, but you have to be another level of incompetent to run in the crops when it's been a year and a half almost that your dad has been teaching you to NOT make a sound. And he is not deaf, so he should be able to grasp that.
* Let's get to the elephant in the room: A BABY???? You crazy, guys?
Also, since I mentioned people with hearing issues, I would really be interested if this was an interesting movie for you, apart from the plot holes above.
