Why is Alien Covenant a GREAT movie? The True Meaning Behind Alien Covenant
(Spoiler Alert!)
(DISCLAIMER: English is my second language. I only watched this movie once. Lots of details are blurry now. Please help correct my English and the details. Thanks.)
Alien Covenant has been criticized pretty badly, the ratings are not good. Some mainstream media even argue, should we still pay attention to this series?
Keep reading, I hope you will come to the conclusion like I did, that we should DEFINITELY pay attention to it.
I have to confess, I have never been a big adrenaline fan for entertaining horror movies. I watched some of them mostly for visual effects and talking points. I watched Prometheus for the same reason. (Also because I am a space exploration fan.)
When I was half way through Alien Covenant, I couldn't watch it any more. Characters made so many unparalleled stupid decisions. So I waited and watched them die one by one without any empathy. I even laughed out loud when I realized that I was fed up by their stupidity. That's when I was struck by the lightning.
Isn't that THE elephant in the room?
In Prometheus, audience laughed at Dr. Shaw when she forgot to run sideways to get out of the alien spaceship's way. I wasn't sure whether I would be so dumb and panic if I were in that situation.
In Covenant, I saw some similar mistakes made in both movies: why not send a rover like Curiosity or a disposable droid down first, to get a full report first. Why break the quarantine protocols again and again and push your luck so far by inhaling the alien spores, touching the unknown species, and test how many lives they have. Some of even worse decisions are, Tennessee risking all the 2000+ lives on board to save his wife. (She died BTW.) His crew gave up easily without a fight to keep him a clear mind. And on and on.
When I realized these mistakes could have been easily avoided from a bystander's point of view, but might be difficult for the people in that situation, I further asked myself, is that really so?
What I learned from Prometheus is, what if our creator is very disappointed at us and doesn't really like us? Why? According to the movies, obviously we are not the smartest species in the universe. We make stupid mistakes knowing that our behaviors will inevitably lead to horrible consequences, but we are determined to do so anyway. (Look at the real world we are living in! We are seriously arguing if the earth is flat!)
True, in the movies lots of deaths could have been avoided with knowledge and reasoning, Some other deaths, you just can't escape them. They are not all the characters' faults. But their deaths were direct consequence of the bad decisions that others made for them.
So, what exactly is this Alien? I think it's a metaphor of cold and hard principles/consequences of nature. You can cheat it for a while, but you can't escape from it for ever. As soon as you make one mistake, the cold principles may not kill you immediately, but will eventually come and get you.
There are many other angles of this story. (You are welcome to share.) Actually lots of director's ideas are expressed very well through David's monologues. (Talking is almost always my favorite part of the movies, maybe this habit of mine came from Matrix Reloaded. ) For many times, he clearly expressed his disgust towards human, even his creator. He came to the conclusion that wiping human out, or at least stopping them from becoming immortal or interstellar species is the ultimate good, and the only logical thing to do.
So, in these movies, there are three separate parties, human, AI, aliens (principles/consequences). Now it's very clear what the director is trying to tell the audience.
Look at what you've done, you dumb idiots. None of us can escape the inevitability, no matter how eager you are, how hard you fight, how long you are surviving for now. We will all be kissed by death at the end. The only thing that can surpass us is AI, it might be less humane, it might look like a jerk, but at least it doesn't try to fool itself with alternative facts. At the end, AI will dissect us, analyze us, and try not to make the same mistakes that its creator made to themselves.
And, this is not a space horror popcorn movie, this is a prophecy, human! If you don't get it now and start acting wisely, you are indeed as dumb, if not dumber, as these dead people in the movies.
In thousands of movies where human fights non-human, we all came to believe in some degree that human species are intelligent, sympathetic, willing to sacrifice for the greater good, which make it superior to other species. While other species don't serve any purpose but simply are driven by basic instincts like hunting and eating. This assumption stopped us from understanding the mastermind behind so many great Sci- Fi classics, Ripley Scott, who definitely spent much more time than lots of us, thinking about humanity and the future of our species.
10/10 for brutal honesty.
