Easily a half hour too long, but otherwise, very well done. It could have done with a lot of tightening up: extraneous scenes; too much character building, but I think that's the French, though. They love their personal drama to the point of distraction for us Amurcans. The story parallels the MCAS conspiracy, but changes it just enough to avoid the lawsuit. I recently watched the Boeing, McDonnell Douglas documentary, and boy, was that an eye-opener. Brings a whole new meaning to corporate greed (BP excepted). This story threw in the personal life of the Black Box listener who worked for BEA, the French version of the FAA. It shifted the evil empire from a direct shot at the manufacturer to a sub-contractor., and added some red herrings and violence to wake up the audience who might otherwise have fallen asleep. Overall, if you can deal with subtitles, I highly recommend it, and I also recommend you watch the Boeing documentary first for a lot of perspective.
