Hangar 1" is one of the worst documentary series about UFO phenomenon, I have ever seen. It's an absolute disgrace. Awful editing, cheap animations, showing little original footage (sometimes they use fake footage when real one, actually, exists) and most of all, horrible analysis of evidence and facts. The whole series is presented by a group of so called "UFO experts" who do nothing more but project their assumptions, with little critical thought and questioning. There is little scientific analysis from scientists and technicians, whatsoever. Manye cases have been even debunked long time ago, so why do they still keep repeating the same stories over and over again. Such series does more damage, disinformation and ridicule than good for the proper scientific research of this phenomenon. To compare, there are great UFO series such as Alien Mysteries (2013) or Close Encounters (2014)- they are with high quality animations, well detailed recreation of events and. They are well edited and are full of interviews with eye witnesses. Contain decent analysis with little assumptions. They give clear view of events and leave it to the audience to decide what they think. Complete opposite to Hangar 1.
