10/100. No, you read that right. This movie is terrible and poorly conceived. (SPOILERS)

Rating: 1/10 (14 April 2018)

This film has so many problems that it will be easier to review in sections:
1: Sonar?
The aliens are blind, possessing extraordinaly sensitive hearing, yet they cannot sense the world with sonar. Sorry, what I mean to say is that the aliens have "selective sonar", which seems to work only when it's convenient for the plot and the characters. Throughout the film, the aliens make clicking sounds - resembling echolocation sounds, of course - and they are constantly banging things in thier immediate environment to get some sort of echo-impression. Or so I thought...
The inconsistency is as follows: In situations where the aliens are running towards a sound (eg. in the forest scene by the bridge at the beginning of the movie), the aliens can anything that might stand in their way. For example, the first alien speeds through a forest of trees without hitting a single one. Yet in the same scene (and in every other scene) the alien is unable to see any humans moving. This also is the case when the human is standing right in front of them.
2: No weakness? Come on...
The aliens have one dominant sense: hearing. All hearing works in the same way (I don't care if you're a human or an alien, or whatever): tiny hairs vibrate in the inner-ear and the brain translates this vibration into the perception of sound. Loud noises can do damage to those little tiny hairs - you can even target hairs at a particular frequency, and they don't grow back. If humanity wanted to survive, couldn't they have just sent out protective earmuffs to the residents of their localities along with some instructions to soundproof their homes? Then couldn't they have proceeded to make loud and deafening noises? Once the aliens were deaf, couldn't humanity just have cultivated them as livestock? Made tasty burgers from them? Well, apparently not.
It's also worth mentioning that a home-made hearing aid (which didn't even work, by the way), a shotgun, and Emily Blunt, of course, was enough to kill one of these aliens. All things considered, I'd rather have one of these aliens in my house than say... a grizzly bear. Those things won't flinch from a stupid hearing aid. They'll tear you to shreds, shotgun or not.
The military really should have figured this all out. Immediately. They should have tested everything here within a period of 24 hours. Also... how did these aliens survive a meteorite landing, or whatever journey they took through space to get to earth? They're clearly carbon-based lifeforms that are full of water, just like us.
I have so many questions, but no answers.
3: Character believability?
a) I'm sorry, but after the boy dies in the beginning, there is no way that those parents are having sex in the near future. Yet, they do. Soon, they're pregnant again. The world seems like a great place to raise a baby, doesn't it?
b) The teenage girl is not remorseful for basically killing her little brother. She goes back to his grave. Big deal. It looks like they all did that. She seems more concerned with her father hating her. So concerned, in fact, that when her father is about to die at the end, and says 'I love you', she kind of ... smiles. Who smiles just seconds before their father is going to be ripped into pieces?
c) Why doesn't the dad cause some other distraction, rather than screaming at the top of his lungs? All those tools in the shed nearby would work very well as distractions. Come to think of it, there is a car horn in the truck. Why don't the kids stop their father from being maimed by distracting the creature?
They could just play a game of piggy in the middle, throwing sounds back and forth. The alien is so dumb that it would run itself into a hole and die.
4: Unnecessary things and coincidences
a) The man in the forest who screams at them, just because.
b) Hearing aid hurts the aliens.
c) the fact that the girl happens to come along right as the boy is going to be found in the cornfields by an alien, and then b) happens.
d) b) happens a lot.

4: I could go on, but I can't justify it. I actually made an IMDB account just to say this movie is terrible. All you people giving this film 10/10... I don't understand you.
10/10?
Please go and watch the original ALIEN movie by Ridley Scott and John Carpenter's THE THING. Those two films are horror/suspense done right.
Kind regards,
