For a documentary that was intended to make a sweeping overview of humanity's accomplishments in space, this sadly felt more akin to a shallow compilation.
Where I expected a thorough exploration of most of the achievements astronaut have staked there lives on, it was more akin to a jumble of subjects that didn't have a proper thematic connection. Sure, most of the subjects discussed within this documentary have their function such as for example the bit about the simulations that astronauts have to experience.
Long story short, I expected a stonger view on the missions themselves and the people involved and how their work in impacted their time for the better. It is there within the documentary but it deserved way more limelight than it did in my honest opinion. The bits about the future explorations toward Mars were very interesting though.
It works for the amount of time it takes to watch the documentary.
6/10.
