Whether or not UFOs exist isn't the question. Their existence is documented by film, photographs, radar, and by credible eyewitness accounts. The problem is that we just don't know what they are, who made them, and why they are in the sky,
If a new species of bird were as heavily documented by UFOs and UAPs are, biologists would be asking for grants from universities to study and name them. However, what happens in the skies of this country is the business of the US government and not colleges and universities.
The impetus for this four part docuseries was the 2017 New York Times publication of an article called "Glowing Auras and Black Money: The Pentagon's Mysterious UFO Program." The article revealed that the government acknowledges UFOs and considers them a serious enough problem to dedicate serious resources into investigating them.
The series is NOT one of the hundreds of pseudoscience on cable television programs that purport to tell the "truth" about the impending alien invasion. Nor is it four episodes of satire making fun of the people who study UFOs. In fact, it goes to great length to show to what extent the people who see UFOs are ridiculed, and to remind the viewer that "there is no more credible witness than a trained Navy flyer" while showing a radar view documenting what the Navy flyer saw.
Instead, the series is a straightforward presentation of the evidence we have, and the ragtag group of eyewitnesses, astronauts, and billionaires trying to know more. On the one hand, it's frustrating because most of us have heard at least one of the stories at one time or another. It's hard NOT to believe a Navy pilot and most of the citizens of Phoenix. It's hard to invest the time in the series and come away knowing little more than we knew going into it. On the other hand, this is a docuseries, not a Netflix sci-fi miniseries.
But, what is the alternative? The U. S. government knows but it won't, as we found out in the infamous Obama interview, tell us. Perhaps the only way to find out how this all works is to keep presenting information like this until we know.
