I did find this season much more "black and white" - Anne is young, confident and sexual, Charles is shy, distant from his family yet clever, the Queen is pretty business like with little emotion, Camilla - wiser, experienced a bit of a tease. Unlike the previous 2 seasons when it felt each character was fully formed this seems more like Channel 4s slapstick comedy "The Windsors" with extreme characterisations, almost caricatures of each family member.
I also feel like much more the facts were embellished upon (or at times down right made up) to add drama rather than taking historical facts and making up what may have one on behind closed doors about it. This is something that as we approach more recent times which more people can remember is something the Crown writers and researchers are going to have to be more careful about.
