One of the best movies ever, love all the details. No plot holes 👍

This is a great movie, if one were to take the time to watch the movie, then all their questions will be answered. Where did the sand come from? Well the girl laid on it in the beginning, guessing that's where it came from (beach). Why not live next to the waterfall? Well it's slippery and they had already settled at the farm with crops to be attended to, a defense system, and it would make a lot of noise moving to a waterfall. Why didn't the monsters hear them walking and doing stuff in their house? Well they padded all the rooms as seen with the two children towards the middle of the movie, the monsters are mobile moving from one place to the next, and because nature will mask their quiet noises with it's big ones (birds chirping, raccoons, dogs, waterfalls, etc.). Why didn't scientists figure out high frequencies hurt monsters? The aliens effect electricity, seen in how lights flicker when they are near. The cochlear implants produce no sound, the aliens effect her hearing aid by increasing the electrical output for the feedback loop. Knowing this one can determine that the aliens are effected by electromagnetic sound waves. Therefore, they are kinda messing with themselves by accidentally effecting her hearing aid. I do have to admit the hearing aid concept is complex, but if one were to look hard enough he/she would somewhat understand. I really like how this movie does not explicitly tell people answers, but instead let's viewers figure it out through observation. If you don't really watch movies, meaning observing as many details as possible, then you will not like this movie. This isn't the regular blockbuster movie, it requires actual thinking. But, if you do search for details and recognize how they all fit into a bigger picture (moral of the movie=family), then you will like this movie 😁.
