Plot hole galore
The movie suffered from some logical inconsistencies and the alien movie trope that militaries have to be absolutely incompetent.
They clearly were able to operate aircraft and drones and understood they are attracted to noise. Yet they didn't corall the monsters to isolate them (also, in the previous movies a year on, militaries didn't realize to use sound weapons... on creatures deadly focused on sound).
It's also weird how the creatures don't attack the noise they make themselves. They clearly communicate with each other, but what about when they knock something over with their body.
As much as I enjoy the films, I've also thought the monsters should have just been magic. It's too hard for me to justify their existence due to how they break physics.
I fully believe a modern military could absolutely take down the monsters from a quiet place. Even with the initial chaos slowing them down. A modern navy would fortify a few islands and then slowly work on defeating the creatures with all their weapons.
Hell, they could have aircraft blasting music to draw creatures away if it came to it and bomb areas.
But none of that happens.
