This show does a wonderful job looking at the UFO phenomenon critically while also putting you intensely in the shoes of those who have experienced this stuff. "UFO" also lays out all the moving parts, spinning the tales of believers and non-believers alike and leaving you astonished at the topic's complexity. Moreover, clarity is gained from this in terms of understanding why no one has solved the mystery yet. You may find yourself believing in all the possibilities without resting your stance in any one side of the issue. For example, the arguments presented for UFOS being secret government technology is very strong in this series, but that is not without marveling at the arguments for extraterrestrial origins as well. Even though I was up to date with some of the material covered in "UFO", I was glued to the screen the whole time. Finally, you will encounter some of the more exotic UFO phenomena in this series (abductions, skinwalker ranch), but I'd advise you not to turn back from this roller coaster ride just because it has a few wild turns.
