This is a mortifying (yet outstanding) production, mostly because it may go far beyond a mere fiction, and is "possibly" significant. This is definitely not a film for just about anyone, not even for the average science fiction fan. In addition, I dare say that this film may be classified in the same overall mysterious category, which I attributed to the 2018 production "UFO" (which is a movie about a college student and his mathematics professor, who investigate a series of mysterious sightings reported at multiple airports, believed to be UFOs - silent alien ships which appear sporadically on Earth, expecting a specific, highly complex, and significant message from Mankind)
