• This movie isn't about proving that the UFO phenomenon is real, so much as providing an answer to aspects of it that do appear to be real. I've been interested in the phenomenon since I was a child in the 60s and 70s and there were several UFO "flaps" or excitement over a number of sightings. I noticed early on that the phenomenon seemed to be polarizing -- the experts seemed to fall into one of two camps:

    1) True Believers who seemed to accept everything hook, line, and sinker, and often expanded the accounts to include widespread, amazing conspiracies and incredible levels of alien presence and collusion with governments -- and made lots of money with books.

    2) Total Debunkers who denied that there was anything at all unusual going on, just perhaps some rare but known phenomena -- swamp gas, mass hallucinations, nightmares, maybe ball lightning. Mostly they seemed to just read reports second-hand and insert such "explanations" for anything and everything and assume that was that. They probably didn't make as much money on books, but one or two did write books and frequently appeared as "experts" in TV coverage and documentaries. Both camps seemed to be wearing blinders, dismissing some things that shouldn't be easily dismissed while accepting what they wanted no matter what. However, I noticed two of the researchers who were highly qualified and did extensive, close research changed their views over time and came to a third, arguably more balanced view: in rare cases, the phenomena was real, not like ordinary known natural phenomena, but also that they didn't fit any conceivable visitation by aliens or humans from the future. Perhaps this is just another form of biased conclusion, but it seems more reasonable to me than the first two, and this movie gives a good introduction with a number of reasons for rejecting the extreme views and goes further, pointing to facts which make the most sense if there are some real phenomena which are caused by neither aliens nor known natural forces. It does however, accept the explanation that the Roswell "crashed UFO" was a Cold War listening device and weather balloon, and that most of the cases have natural explanations. Personally, I suspect the whole story is a bit more complex, with secret government experimental projects playing a larger role than this movie suggests, but overall I think it does a service in presenting a different way of looking at the subject. You may not agree with the final answer that is presented for the cases that go beyond easy explanation by natural events, but if you've only known one or both of the first two views, you really should check this out and at least allow your mind to ponder that there may be "...more things in heaven and earth, ...Than are dreamt of in your philosophy." (Hamlet, by Shakespeare, as if you didn't know).
