I’ve seen the first and some of the second season.
I did hear somewhere that Her Majesty watched it, but I’m not sure if that’s true.
I heard the same thing about Her Majesty watching it, but if it was on the Interwebs, it has to be true, right? ;o]
All in all it was pretty good, but the third season (I think) they changed the actress who played the Queen, and she was much better for that period of Her Majesty’s life, I thought. I don’t think the original actress would have done as good a job.
It’s a good series, all told.
