This is a movie that demonstrates that the true Monsters are humans. That the director doesn’t even call the antagonists alien (or human) is telling. I believe that the message is that we as the human race are so rapacious and self centered that we will do anything to benefit ourselves, even if it ultimately leads to our demise. Perhaps, even when love is involved.
I am truly delighted that I watched this movie. While it has a Sci-Fi and horror label, it is actually about the human spirit...with some infrequent large shrimp like creatures that (spoiler alert) show so much more compassion for each other than the humans in the film.
It is a masterpiece of human nature. Absolutely loved this film.
