3. Unacknowledged
Rating: 7.1
Up next on our list of best alien documentaries to watch on Netflix in 2017 we have Unacknowledged that is the newest UFO/Aliens documentary streaming right now on Netflix. After its release, the documentary has managed to gather a lot of admiration and fan following. It focuses on historic UFO documents kept secret for decades, and why governments have been keeping it secret almost religiously for so long. It’s a very interesting take on the whole subject of extraterrestrial encounters.
