I was on Harry and Meghan's side before I read his book. And in large part because of the disgusting and shameful way Meghan was treated by the British press which is a valid thing, whatever else is going on.
But after reading and re-reading Spare, I think I have a better impression of the Royal Family than before.
With Charles we learnt that he always came to tuck the boys in at night, never forgot that Harry needed the door open because he was afraid of the dark, and it seemed from Harry's own words that he did try his best to be a good and consistent parent within the framework of what he knew.
Harry's anecdotes about Kate made me completely change my opinion of her. It seemed like Meghan was trying to force a friendship between them (the lip gloss incident, the baby brain incident), when Kate had been around the Royals for a long time and would have learnt to be cautious of new and over-friendly people. And then when she did initiate a conversation with Meghan at Trooping the Colour she got a flippant one word response. And Harry thought Kate was in the wrong for that?
With William I just think, there are worse sibling dynamics. It's normal to want to be your own person at school, it's normal to want a best friend as best man, it's normal to not want to stay out all night when you have a newborn at home. Harry seemed angry that William wasn't the brother he wanted him to be, but ultimately that's not William's problem. At the end of the book William tells Harry he loves him and wants him to be happy, the kind of emotional reaching out Harry said he wanted, yet it seemed like he didn't try to meet him in that moment. It was also William who tried to have conversations about their mother which Harry rejected (which would undoubtedly have been one of William's crimes if it had happened the other way around, also the North Pole trip that could have caused him to miss William's wedding, imagine if William had done that...)
Even Camilla doesn't come across like a villain, once Harry has explained that there are people around the Royals who manipulate them and play power games with them. She as a new member of the family wouldn't have been immune to that. Perhaps she thought she could speak to her staff in confidence. And maybe a Prince gets to be shocked that his room was repurposed when he left home, but it's a pretty normal occurrence for most of us.
The book is fascinating as a historical document and the first time a Royal has (voluntarily) been so forthcoming and honest, but it's striking to me that his family just... don't seem all that bad, except the one obvious exception. Whereas Harry seems unaware of some of his flaws, like his blatant hero complex. (The motorbike anecdote made me cringe.) He's so ready to vilify his family over relatively normal things and not-so-normal things that he admits are out of their control, that it makes me wonder how things will pan out with Meghan. Once the dust settles and all the stories have been told (with no access to new ones now his family know he's an exposé writer) and he is missing the hunting trips and the summers at Balmoral, he will only have one person left to put in the role of villain.
