Regarding the film, the director may be expressing that the abuse of technological civilization is the monster. The octopus is brought by airplanes, and octopuses only attack cars, airplanes, and people who use these things. The Mexican tells the protagonist that if a person meets an octopus and does not move, he will be fine. Even the use of a small technological device such as a camera will anger the octopus and be killed.
At the end of the plot arrangement, the heroine seems to say out of an unknown premonition: I don't want to go back. It is also insinuating that people may only need some basic technology, and that too advanced technology is a "monster". In addition, technology is a single-edged knife, and every technology will cut off a human instinct without pain.
PS: It should be good if it is written as a novel.
