There is no shame....
...in looking things up. I realize, because I too am guilty of it, that people love to jump on these boards and say a movie didn't make sense or that it was silly. It doesn't hurt, after viewing a movie to read about where the movie was made and then maybe research it's folklore. The opening quote is not actually a Bible quote, but resembled Genesis 6:1, so I knew the angle of the movie immediately. Having just seen Linthamos' Alps (and Dogtooth), as well as Thale, I was aware of some of the folklore, but Borgman was different in many ways. It is a hilariously funny movie in one sense, but it is a metaphor for the world's crumbling society. Where the haves are so concerned with appearance, while the have nots never stand a chance. Borgman flips this on its head. Anyone who has seen it, realizes just how ridiculous it is that a simple bath and haircut can trick someone so easily. I think if you watch Borgman from an American point of view, you will not understand the intricacies of the fable, but literally 4-5 minutes of research, even after the film is over, can bring films such as this, so much more depth.
One thing I've always been amazed by with horror fans, is when films are heavy on psychology, philosophy and folklore. People like and hate them, just like other movies, but usually for entirely the wrong reasons. I never realized just how much this was so, until I saw comments about Martyrs. There are fans, with multiple college degrees and well versed in history and philosophy (aka actual friends of mine), who believe it's one of the greatest horror movies of all-time....and don't understand one shred of its symbolism and metaphorical contend in regard to French government. Before you bash me for being pretentious, I'll explain again. I did not understand all that was in this film, but three googles searches, one a refresher on Genesis 6:1-8, nephilim and the Dutch class structure. Like I said, there is no shame in not understanding something, but to bash it, without researching why it made no sense, is in my opinion, just laziness.
