I can see why some people would find this relatively boring or empty compared to the directors' other works, but I think that mostly comes down to taste. I don't think a documentary on space flight is ever going to be quite as personal or emotional on a human scale as something like Free Solo, due to the huge scale of the teams that are involved and the relativey small impact each individual has. Things like this don't really have a single personal, emotional story to focus on. Although the directors try their best with Elon and the astronauts, at the end of the day they're mostly forced to sit around and hope things go well as opposed to overcoming personal obstacles in a dramatic and cinematic way, which I think is the feeling that many people miss with stories like this. But for the rest of us, the humanity-scale emotion of space flight is more than enough to make up for it. Also, the fact that the directors have to rely on official, and often sterile, footage from NASA and SpaceX doesn't exactly help, but I think they did a really great job with what they had.

Fantastic documetary. If you're even slightly interested in space exploration, it would be silly not to watch this. A lot of really cool footage we haven't seen before. Good job Netflix!

Netflix SpaceX documentary — the launch and return sequences are genuinely tense. Musk's presence is more hagiographic than critical. Strong craft in service of promotional material.

Even though I've followed SpaceX and have seen their other documentaries, I still have a fun time watching them.

I just hope I am alive long enough to see us being on Mars.
