Having watched it I kind of feel as though I owe some kind of an apology to the captain of the a/c. In previous programmes relating to the accident which formed part of my ATPL groundschool and MCC training, it was always inferred that the a/c could have been landed (if overweight) had the captain not elected to dump fuel, thus seemingly wasting time. This led to many a classroom debate on the 'correct' course of action.
The programme seems to have been at pains to point out that regardless of the actions taken by the crew, insufficient time was available from the problem becoming apparent to the crash occurring for an immediate diversion to Halifax to have been of any use.
