If you want to see really interesting footage of how this was accomplished, this is worth watching. If I were reviewing only on the footage, I'd give it a 10. But it should be noted that there is no narration, except a few random blurbs of NASA/news reporting and politician speeches starting around 21 minutes into the 30-minute runtime, no other audio than background sound effects. There are also no closed captions. It would've been really nice to hear something about what procedure was going on in a particular scene. I can imagine the deaf or hearing-impaired community would've really appreciated that.
