Netflix's "Bird Box" is a survival movie that follows the character, Malorie. The movie doesn't show any creatures, like zombies, which humanity has to fight against. Instead, its version of an apocalypse leads people to kill themselves if they "look" at this mysterious force.
Malorie's sister, Jessica, falls victim to the force as they drive from the ob-gyn (because Malorie's pregnant). The audience sees Jessica's eyes mutate, indicating that whatever it is she saw has taken over her. The city goes chaos, with cars up in flames and corpses lying around. We then find out that this sight is different for everyone because it manifests their "greatest loss" or desires. The main survival tip of the movie is to not look. "Bird Box" continues from there and ends with Malorie and her two children in "paradise."
My theory is this: the movie is about Adam and Eve.
In the "Book of Genesis," Adam and Eve eat from the tree of knowledge, which God forbade them from doing. A serpent then tempts Eve into eating from it, and Eve offers the fruit to Adam. After eating the fruit, they see that they are naked, a look that causes them to feel ashamed and to fashion together things to cover themselves. This disobedience leads God to exile them from the Garden of Eden, furthering their (and our) relationship with God.
The movie doesn't allow the characters to look because doing so leads to suicide. There are some people in the movie, however, who want to look. They don't commit suicide; but, they make other people look. Devils have possessed these bodies. They are scary and reckless. They are violent, using force to do their job. Looking is a way of obtaining knowledge, and those who look see a false reality- false knowledge. This "creature," like Descartes's evil demon, masks reality. A character, who was helping the fallen Malorie get up amongst the craziness on the street, sees her mother after looking at the creature. We later find out that her mother has been dead for a while.
This creature manifests temptation- the serpent in the Garden of Eden. It entices the lookers and possesses them to kill them. The movie provides for the point that we distance ourselves from God because we then stop to see true reality by looking. We are seeing what is not necessary. We are not seeing the good and beautiful that God had intended; just like Adam and Eve, we strayed our focus away from the beauty. Succumbing to temptation marked the fall of humanity, making way for greed and walking further away from the good and beautiful.
Girl and Boy, named so for most of the movie, are the Adam and Eve who never gave into the serpent's enticement. This is so because they were taught not to look under Malorie's assertive guidance. They were born in the emptiness of civilization, not having knowledge of this world- as if it's a restart to being in the Garden of Eden. The three survive the movie's obstacles, ending up in what looks to be the Garden of Eden on Earth, a place that has good and beautiful.
In conclusion, "Bird Box" portrays the view wherein the world has completely distanced itself from the good and beautiful. It comments on greed and corruption, taking into view the temptation of looking at things other than what really matters. The movie's world has gone to shambles (a parallel to the end-of-the-world picture), with strife taking over. Love re-enters as the three survivors enter the "Garden of Eden," starting over from the "beginning."
