Absolute garbage, this documentary is very misleading and doesn't hone in on exactly what the problem with the 737max airplane was.
The main reason why the planes crashed was an aerodynamic design flaw that was augmented with software to compensate these design flaws. The documentary would lead you to believe it was a production qualify control problem but this wasn't the cause. The documentary has no direction and relies heavily on the families hurt to validate itself. It seems like it was put together by people who didn't bother to educate themselves about aviation systems and history. Overall very disappointing. A quick Google on the real cause and reasons will save you the time.
