I am not sure this is a spoiler, but just in case I am putting these thoughts inside a spoiler button. Most of what is revealed by the show is already in the public domain.
I have to start with this thought. Harry is the most privileged of the privileged on this planet, and probably any planet, but by virtue only of his birth to two super privileged parents. His beef seems to be he doesn't have enough privilege because he had the great misfortune to be born after his brother William, the future king. Harry is just a "Spare" which is the title of his forthcoming book. So Harry has embarked on a royal temper tantrum. Somehow, he manages to go through all 6 episodes without realizing that everything he has, everything he gets for free, which is incredibly substantial, is all the result of his fantastic privilege.
The couple's main complaint appears to be that they get negative press in the British tabloids, especially Meghan. They pretend it only happens to them and the British tabloids aren't cackling at other members of the royal family as well. (Too bad Princess Margaret is dead because I am sure she could educated them a bit). My goodness this takes an incredible amount of ignorance. But worse than that is while they complain about how the tabloids have treated them, they are using Oprah, Netflix, biographies and other media venues to attack the rest of the royal family. And the attacks are not backed by anything other than innuendo and suspicion. Even when members of the royal staff dispute the H&M accusations, H&M just dismiss it as royal propaganda and witness intimidation. They go so far as to blame Harry's brother William for a witness's testimony against Meghan's lawsuit of the Daily Mail tabloid.
The weird thing about the series is all the videos of Meghan and the royal family together. There are no signs anywhere of anything other than acceptance of Meghan into the family. They tried to help her deal with the media and she took it to be them trying to control her.
They also have a beef with the paparazzi, who follow them everywhere and won't leave them alone. And yet, they insist on constantly stirring up controversy by spilling family dirty laundry in the media that they hate. They work hard to get as much attention as possible. At one point they claim they were looking to move to South Africa or New Zealand to get away from it. Of course they didn't. They moved to Los Angeles and stayed in the mansion of Tyler Perry in the Hills outside Hollywood, for free! I am sure the paparazzi wouldn't bother them there! If they had moved to New Zealand, I am sure they would get very little attention, but I am also sure that would make them both very unhappy because clearly, attention is what they seek - as long as it is the kind of attention they like.
Why do I dislike Harry and Meghan? Because to me there is no worse sin than airing family dirty laundry in public. Harry even admits having close relationships with Prince Prince Philip and Queen Elizabeth, his grandparents. He couldn't talk to them in private about his issues? or to his brother? H&M have turned spilling family secrets into a money making machine. The only question I have is why hasn't King Charles, or Prince William, cut them off completely. No one deserves ostracization from the family more than H&M.
Charles and William keep offering the olive branches, Charles is going to invite them to his coronation, but in return Harry is publishing another tell all book which supposedly dishes even more dirt on his family.
