I watch Air Crash Investigation quite a lot and the format here was very similar - they even used some of the same industry experts that ACI does. One thing they always say on ACI which was relevant here is that it is very, very rarely a single event or decision that brings an aircraft down, there is nearly always one bad decision that leads to another and then another.
As the guy said last night, when the AP disengaged he didn't need to do a thing, just take the controls and keep the aircraft in level flight.
