Question: Where does all the power for monitors and lights come from? I assume power is down, a diesel aggregate would be too loud and hydropower too weak. Solar cells?
Plot hole: The aliens seems to be very strong, but not using technology at all. How come they defeated for example tank units? Doesn't look like they can penetrate steel with their arms.
Suggested correction: The aliens also demonstrate the ability to run extremely fast, easily able to outmaneuver a slow-moving tank. They would most likely jump on the top of the tank or rip the treads off, considering they still are extremely strong. They would also quickly jump onto a helicopter and take it down. As for other vehicles such as jets or aircraft carriers, the aliens either would have attacked military bases or taken the fight out to sea in ships. Whatever the answer, that particular element of the aliens is a large amount of possibilities, not a mistake.
If a waterfall can disorientate them, so would a jet engine or gunfire.
Loud sound doesn't disorientate them; it just "hides" quieter sounds.
Something they teach in the military is the "ghost walk" - how to move silently. As the newspaper cuttings suggest, the noise angle was known about while there were still working printing presses, so it must have been a slow event. And a helicopter gunship can engage from up to 1km away, that's a long jump.
Yeah, how does the military never tried to use loud and/or high sound to defeat them once they found that they hunt using the sound? But to be fair they seem to be everywhere, so maybe they attacked in very large numbers.
That's actually clever (assuming the aliens didn't rip everything apart before coordinated strikes). Have some jets fly at low speed and A10s behind light up the space.
Factual error: Grain engulfment is not depicted in a scientific manner. It is not possible for engulfment to happen without a valve being opened at the base - which has not been shown in the movie when the boy falls in the grain storage. It is very unlikely that two engulfments will happen so close by in the same storage - if so, they will converge quickly. But, the movie shows both victims help each other one by one. They succeed in 5-10 seconds. Engulfment become entrapment in less than 20 seconds and require more than thrice the body weight to pull some one out (unlike one kid being able to pull other one out while both are on the grain). Finally, they both sit on the door and avoid entrapment.
Suggested correction: It's possible for grain to look sturdy but not be underneath so the engulfment could have possible. But you're right about them not being able to pull each other out.
Well observed. It's a factual error.
I jumped into grain hundreds of times. It is not possible without the grain moving underneath.
Factual error: The son's death happened in 2020 and it was day 89. On day 473, the mother writes in the calendar and it's Wednesday 3 October. So, the year must be 2021. But 3 October 2021 is not a Wednesday, but rather a Sunday. (00:26:00)
Suggested correction: It was October 23rd. And it's a Tuesday. The next October 23rd that's on a Tuesday is 2029. So still wrong but I'm curious as to how you got a year in the first place.
The year was on the memorial cross they left that shows 2016-2020. That's how the commenter got the year. As well I read others spotted dates on some of the newspaper clippings which wouldn't match the time frame.
Factual error: Emily Blunt takes her blood pressure manually, pumping up a cuff but not listening to her pulse with a stethoscope to get the reading. Not possible without a new style automatic BP machine which would have made noise.
Suggested correction: This is simply not true. The style of BP monitor that she uses is the way all BP monitors used to work.
The way you use a manual BP cuff is by listening to your pulse with a stethoscope while you pressurize the cuff. Your top number is the pressure you hear your pulse stop, and the bottom number is the pressure where you hear it pick up again.
Suggested correction: It is possible to read the pressure by such a machine as shown in the movie after some practice. The needle or the indicating hand slightly skips when it reaches the read pressure range.
That's inaccurate. The pressure at which the gauge jumps is often different than the pressure at which the first Korsakoff sound is heard.
Suggested correction: You can watch the needle bounce with the pulse on any sphygmomanometer - not as accurate as with a stethoscope but would work just fine.
Corrected entry: Though the film takes place over many months, the crops in the field near the house never seem to change appearance.
Correction: Actually, after 89 they skip to Day 472 and then, it's just 2 full days of action. So, I don't think farm appearance is a mistake here.
The corn wouldn't still be green after more than a year in the field. And they couldn't have planted earlier that same year, as the noise would have attracted the aliens.
Answer: While it's never directly addressed, one can see solar panels on the roof of the farm buildings at several points in the film.
There could also be wind generators (not seen).

While in theory there could be wind generators, I find this unlikely since they tend to make noise. The creatures would have attacked them pretty quickly.
