Fine horror/thriller that doesn't work out a few glaring plot holes

Rating: 8/10 (20 October 2018)

The premise is great: nasty aliens are around that kill anyone who makes noise, so the farm family we learn about has learned to live in silence. Luckily, one of their three children is deaf and everyone knows sign language. We arrive in the 79th day of the alien invasion and as the family strolls along its sand-muffled walkway to the nearby village to forage, we see the last of the headlines warning people to be quiet.
The film is beautiful, great child and adult actors using eyes and faces to emote, great cinematography. On a whiteboard in the soundproofed basement of the barn they've moved to, we see writing to tell us three creatures live in the environs. You can't shoot one, or another will show up to kill you. You can't load a gun or a creature will kill you before you can shoot it. The aliens are a sound McGuffin, until they aren't. This is where the film falls down.
Around their farm house is a full-grown crop of corn. They have a silo half full of harvested corn. How do they get the corn out of it? They're eating small-garden vegetables. How are those gardens made and harvested with no noise? Most farms have animals, but no animals are present 79 days in. If the creatures killed them, the humans couldn't have used their carcasses because to butcher an animal makes noise.
OK, so the alien plot holes are many. But, the family dynamics appear genuine. Parents try to give their children as much love and normalcy in a time when nothing was normal. The electronic whiz dad even tries to fashion a better cochlear hearing aid for his daughter.
The slice of life we witness encompasses about a year and a half in these people's lives. So viewers saying how could there be food or medicine on the shelves of the stores in a small town with a small population aren't being realistic. We also don't know how many people have been killed off. It seems to be a significant number.
I think the climactic ending didn't need to be so over the top. We might've kept a wounded character and still had the two people discovering a way around the McGuffin intact. As it is, I'll notch the film down a little for the lack of internal logic. It's still a fine work that I think will stand up to the test of time.
