A " documentary". It's quiet, slow, dreadfully dull presentation is supposed to imbue it with a sense of thoughtful and high academic curiosity. No. It's simply uninspired. Lackluster. With a bare bones cast and nothing to offer the intellectually curious or, heaven forbid, someone looking for a bit of UFO visit adventure.
But what is so unforgivable about this "mocumentary" is that they used actors for the roles of scientists, when there are GENUINE astronomers who could have been infinitely more engaging and informative ( even if it's a fake doc/movie)
If you are indeed interested in scenarios such as this, please peruse the great science channels on YouTube, such as "Cool Worlds" (Dr. David Kipping/ Dept Head, astronomy/ Columbia Univ) or "PBS Spacetime" or literally dozens of other channels who will blow your mind with actual facts and scientific possibilities.
In summation, this bomb of a film is NOT for anyone who values their time.
