Almost Perfect

Rating: 9/10 (20 August 2018)

There were a few mistakes in this movie. For example, when the bag gets caught on a nail in the stairs, I would think the mother would just go back down a step, move the bag, and avoid pulling up the nail in the first place. I know that's what I do when something I'm carrying gets caught. That way, I don't make a hazard.
The next flaw is the placement of the house. This is a common complaint, because living next to the waterfall we see later would make more sense. After all, it would make it a lot easier to live, with sound being blocked by the volume of the waterfall, and it would make having a baby a lot safer.
My final complaint has to do with the monster's weakness. How has nobody figured out sensitive hearing means sound IS the weakness. It might track by sound, but it's like with other animals. They have better hearing than us humans, and as such, feel pain when they hear certain frequencies, e.g. a dog whistle. The same concept can be used here with a single logical step that any scientist working on fighting these things would've tried. There would be sonic cannons or something like that because someone with the resources would've figured it out and built something.
Everything else is absolutely fantastic. The family relations, the mostly realistic decisions (yes, even some stupid ones), and the tone and story direction were great.
Now, there are some who wonder how a shotgun can take out one of the monsters, yet these things have been able to survive military assaults and bombings. These people seem to forget that the thing had just opened up its head (with the hearing organs) after having taken a sonic beating. There was no armor covering it, leaving it vulnerable. It was shown very clearly in the film, and yet people still see this as a plot hole.
Overall, this film was fantastic. Of the three main complaints I have, only the third one really bothered me. The first could be explained away with different habits, and the second could just have to do with the difficulty of trying to make a living place next to a waterfall in order to live safely. I still loved this film, and look forward to seeing similar content (but no sequels) in the future.
