Did the aircraft meet the stabilized approach criterion at 1000 ft?
The only stand-out item would probably be the TL's being at idle annunciated only by the RETARD caption, speed and configuration would likely have been within limits at that point.
If bitchin betty could be programmed to issue a stabilized approach criterion warning - "UNSTABLE APPROACH - POWER LEVERS IDLE", that could have been enough to wake them up and save the flight and some lives. But the suggestion has been shot down already on this thread by the purists who want to see the crew swing and lowly Boeing shielded from any implication that their Auto Thrust design on the 737NG might be less than optimal.
