I watched the first 3 series and enjoyed them ,but I stopped watching just after Princess Diana was introduced into the programme. This was because , in my opinion, the story line developed into a fantasy, but many people, mostly Americans, would think it was true.
One thing that the Crown did do perhaps, was to explain to Americans the differences between the countries of the U.K.
My cousin and I were on holiday in the US in February, 2019, and were speaking Welsh to each other in a quite upmarket shop. The shop assistant heard us and asked if we were Scottish. We explained that we were from Wales and were speaking our native language. She went on to say that she had watched the Aberfan episode of the Crown and was very moved. She did not know that such a thing had happened. We said that is was something that had happened in the mid sixties, when we were in our twenties, and was very poignant feeling that had remained with us since then.
I went on to tell her about the male school teacher who was found with his arms wrapped around 5 of his young pupils. That always makes me cry, in fact I'm crying now as I type this.
I was so glad that through the Crown the wider world had learnt of such a terrible happening that day.
There is a P.S. to this story. Last year, after all these years, my daughter, along with my young grand-daughters, took me to Aberfan to pay my respects. A beautiful summer's day, so peaceful, I treasure the memory.
Sorry if you think I've hi-jacked the thread, I just feel the story had to be told.
