Ignoring the IFE issue as much of that resides in personal taste, it does sound like BA could learn something about reseating passengers in an incident like this. With hindsight (and yes, I know it is always easier to determine the best course of action after the fact), it seems that they could have assigned a crew member to identify the vacant seats before-hand and written each one on a slip of paper as a makeshift boarding pass. A crew member then goes to each person who is to be relocated, hands them a slip, and easy-peasy the job is done, with no scrambling during the relocation.

I understand that this solution may not have come to mind during the hustle and bustle of resolving the emergency and then preparing for landing. However, there is value in looking at a situation after the fact and coming up with a better solution so that if there is another time that multiple passengers need to be relocated, you don't make the same mistake. This kind of post-mortem exercise not only improves performance in similar situations, it also enhances solving other completely unrelated problems.
