I enjoyed this film immensely even though it aggregates a lot of information presented before elsewhere. It was new to me and really interesting.
A lot of reviewers on both this site and Amazon complain about the narrator, whose native language is clearly not English. Her mispronunciation of many English words is a bit grating and I had to rewind frequently to decipher something said. Those speed bumps are no reason to skip this movie though.
Beyond that distraction, the film pixelates badly on a 4K screen. Clearly not upscaled.
The first 10 minutes or so was a bit slow and the film lacked a clear exit strategy, IMHO mailing in the last few minutes. The two hours in between though was absolutely fascinating and I spent the rest of the morning on Wiki checking out the theories advanced. I will definitely be reading and watching more and have recommended this to my father-in-law, who is an actual engineer and a literal genius, for his take.
In the barren wasteland that is post-COVID video streaming (meaning I've watched almost everything worth watching), this flick is worth a few hours on a Sunday morning.
