When Netflix viewers sat down to watch the first series of The Crown back in 2016, most of them had no memory of the events unfolding on screen.
The first episodes were set in 1947, showing the then Princess Elizabeth's wedding to the handsome Philip Mountbatten - long before fans were born.
But it's a very different story with the latest season, which was released last week, as a huge chunk of those tuning in also tuned in to watch the real life events.
Covering 1979 to 1990, it covers Princess Diana's bulimia, Charles's affair and Lord Mountbatten's death.
While the show's writers stress it's fiction based loosely around true events, some of the storylines may be upsetting for many - especially members of the royal family.
Royal expert and author Ingrid Seward claims it was be especially hard for Princes William and Harry, as it covers such personal details about their mum.
Speaking to Mirror Online, she explains: "The whole Diana saga, we never stop hearing about it.

"I do think it's quite sad for Prince Charles and his sons, to have everybody going over it again and again.
"I'm sure Prince Charles won't watch it. It's quite hurtful to be portrayed in such a big drama in a way that he's obviously is not going to find accurate.
"It’s tough for living people to be portrayed in a way they obviously think it completely untrue.
"Imagine if somebody portrayed you or me.
"It would be hurtful. I think the only thing to do would be not to see it. I think it would be a great mistake to see it.
"I sure that's why most members of the royal family haven't seen it, because it would just upset and annoy you."
However, Camilla's friends has claimed she will watch the new series of The Crown.
The show features several inaccurate details about her and Prince Charles's relationship.
The source told Vanity Fair: "I imagine she’ll be tuning in with a glass of red wine to watch it, she has seen the previous series. She has a wonderful sense of humor and this won’t fuss her in the slightest.'
"She has watched it, of course she has and I believe [Charles] has too. I don’t think she has any real issue with it. Her feeling is very much "never complain, never explain"."
Ingrid also stresses that the show is inaccurate and not true to what really happened behind palace walls.
She explains: "I think it's beautifully made and I think it's absolutely fascinating.
"I tell all my friends, it's not a documentary, you mustn't believe everything you see.
"It's got a lot of poetic license. The writer, Peter Morgan, has used that, obviously.
"You mustn't believe it, but watch it and enjoy it. But don't take it as completely true. But they do all believe it.
"Because I suppose I'm something of a royal anorak, I think it's pretty inaccurate.
"But to my mind, it never pretended it was going to be accurate. I think for instance, the character of Princess Margaret is absolutely not what I saw of Princess Margaret.
"I didn't like the way they seemed to have her and the Queen at loggerheads. They were always so close and really supported each other, but it makes it a much better story to have them at loggerheads.
"I'm not criticising the writer. You just have to watch it, but not believe it."
