As far as documenting the technical aspects and/or the flight activities recorded by the FDRs, the movie gets an F. If one is looking at creating a movie that is to influence those who don't care about either of those factors, then it's as effective as any other that ignore the majority of the facts.
What has struck me most is the casual acceptance of false stall warnings. Without this defect in the ADIRU, MCAS would not have operated as it did. What was also uncovered by the investigation, but not dealt with, was the acceptance that there is something called "trim runaway" but without any defining characteristic. If a loose fragment of wire was loose in a trim switch it too would produce a random trim change, but not necessarily be continuous - is that considered "runaway?" What clear indication is there to a pilot to use the trim cutout switches?
