Omissions: Wallace and the other casualty folk from all the local hospitals did a study of the injuries and made not just the recommendations concerning the new brace position, but suggestions on rear-facing seats. No mention made, either, that cabin crew with rear-facing seats were least injured.
No mention either of the new 16G seats being attached to a 9G floor, nor of those pax killed by heavy items hurtling out of the overhead bins (every single one of which detached).
Error: the commentary stated that the vibration stopped "by chance" after they throttled back the wrong engine. In fact it was the disengagement of the auto-throttle that stopped the virbration and falsely confirmed to the crew they had shut down the correct engine. If that is too complicated for viewing public there are better ways of expressing it than "by chance".
But hey, you can't have everything. Can't fault it as a human-interest story, though, which is what the film was primarily, and well-made it was too.
