It will be very interesting reading or hearing what went through the flight deck crews' minds during the final sequence of events. If in fact engine failure did occur, the aircraft would still glide but would very likely hit those unforgiving tetrapods that form the seawall. A conscious decision to ditch, and ditch quickly, seems possible and, IF that does turn out to be the case, it is a decision which will have saved everyone's lives. But I don't suppose those who instantly branded the crew as "crap" will be back to apologise.
