This documentary has been professionally written and the quality of presentation is pretty good. It was entertaining and occasionally very informative. I have no idea what the people who gave this a 1/10 were watching, but it wasn't this. So taking into account this documentary and other books and documentaries over the decades then we have to surmise that there have been at least 100 UFO crashes, and many of the vehicles and sometimes bodies have been recovered. I'm coming around to the fact that these things have crashed here and organic and inorganic matter has been retrieved. However before we start screaming Government coverup and dive down the rabbit hole of conspiracy theories, lets address the enormous Mastodon in the room. These highly advanced beings that can traverse space and for all we know time and dimensions end up crashing on little old Earth over a hundred times... Nah, I don't buy it, not for a second. Read operation Trojan Horse by John Keel. Whatever this phenomenon is it's been going on for a very long time. To me these crashed vehicles and occupants look more like the items that we might put into a Rat's maze to test them. Let see if the cute critter can eventually get the nut! Its really the only option that makes any sense at all given the changing nature of the phenomenon and its complexity. Some intelligence is testing us, why? I have no idea. Do rats in a maze know they are being tested? One thing is likely, when the rats (us) do figure out what's going on, the phenomenon will probably morph into something else...
