I have been following the case since the start and watched quite a few docs and news segment about it. Every segment so far has been a letdown. You obviously need some years to gain access to all the info Boeing is hiding and much of it is surely still waiting for whistleblowers. The older documentaries are not really worth much because they all have the mystery element remaining in them where no one clearly knows what went wrong or who is to blame. The technical aspects were unclear before. Boeing still blames the pilots while basically everyone else, maybe except for American politicians supporting their industry, are blaming Boeing.
This documentary finally makes it clear WHAT went wrong and why and it becomes much more clear what happened. So for that I really like this doc and highly recommend it. But it's still not super great. You for example have no crash recreation. They mention it, but they never tell us what went wrong from start till finish. It's never quite clear if good American pilots would crash the same plane in the same setting? They talk about the simulations they just never mention the outcome for some reason. So were the pilots bad? Yeah, I assume so, but so was the plane and you should expect all kinds of pilots to fly your plane not just good American ones. That's really nothing new to the airline industry they know that even African countries order their planes. To understand if African pilots are to blame or how bad they are you will need to watch other docs. This was a pure hit job on Boeing so all the blame is laid in one place only. But Boeing is to blame too so it's not unfair to attack them.
Instead of showing us what happened during the crash the doc invites emotional talking heads. Usually they are over the top and ignorant in PBS docs, but here I do feel like they added some neutral emotional aspect that did make the documentary easy to watch for laymen and school children. But info wise it does skip all the details you'd get in any proper investigation report documentary and we probably have to wait 2 to 5 years for those docs to come out. But this is the best one I've come across so far. So right now this is the best you get. But in a few years I'm sure we'll get a deeper and better look into the case.
