I am no expert in UFOs, etc. so maybe I am just demonstrating my naiveté but I found this video truly engaging. As a Christian, I've already heard the assertion this video makes and it was clear from the summary I read on the website, Christiancinema.com, this video supported the same assertion. (avoiding Spoilers here). However, the film gives quite a case history of UFO sightings, showing several eyewitness accounts and different US government papers asserting their existence and not saying they all sightings are explainable as natural phenomena. I fully expected a talking head lecture so I was pleasantly surprised.
As a matter of fact, most of the video is devoted to making a case for the "realness" of UFOs. But it does not do as well in making their case for their assertion and, unfortunately, really resorted to fear tactics to achieve the aim of the video: that is, to convince people that we should not embrace UFOlogy, to avoid it and to believe it has far more sinister origins and intentions than may be apparent. They may well be right in their assertion and it is probably too difficult to "prove" it.
I think as a believer, though, you understand that ideas and philosophies at odds with a historical view of the Christian faith are virtually part and parcel of the UFO experience. So the filmmakers were really aiming at believers who were uncertain about what to think about UFOs or, say, what to tell their children. So, in that, I think the filmmakers really did succeed. And those who believe such negative assessments about UFOlogy are rubbish, would not likely be watching this video anyway.
