I think the timing of the releases looks bad too, deflecting from the Pakistan tour, which hasn't had as many headlines as previous ones. A documentary just focusing on the good work they're doing and how important the royals are to international relations, showing them interacting well with others and just getting on with it would have done them the world of good. Instead this just feeds into the idea that they're dramatic hypocrites (hating the press while using it to their advantage).
Other royals that have managed to turn things around have done it by being good-humoured and diligent, not by complaining-even when they have every right to do so!
