Insiders described the series as "cruel" and "unfair"

'The Crown' season 4 dropped on Netflix this weekend. The series depicts the years 1977 to 1990 of Queen Elizabeth II's (Olivia Colman) reign.

The latest season of 'The Crown' depicts the disintegration of the marriage between Diana Spencer (Emma Corrin) and Prince Charles (Josh O’Connor). It also depicts Diana's eating disorder and Charles' close relationship with Camilla Parker-Bowles (Emerald Fennell).

According to reports, a number of members of the Royal Family are unhappy with the recent episodes.

Close friends of Prince Charles described the series to The Daily Mail as "trolling with a Hollywood budget."

They said that the series was "dragging up things that happened during very difficult times 25 or 30 years ago without a thought for anyone’s feelings."

The insider noted: "This is drama and entertainment for commercial ends being made with no regard to the actual people involved who are having their lives hijacked and exploited."

They added: "That isn’t right or fair, particularly when so many of the things being depicted don’t represent the truth."

A source at the Palace said that the series in particular painted Charles and Camilla in a "very unflattering light."

They continued: "The public shouldn't be fooled into thinking this is an accurate portrayal of what really happened."

An insider added that Prince William "feels that both his parents are being exploited and being presented in a false, simplistic way to make money."

Royal biographer Sally Beddell Smith accused writer of 'The Crown' Peter Morgan of being "almost Trumpian with his alternative facts."

She also said: "There has been extreme and egregious misrepresentation... Viewers should not be fooled. This is a 'Downton Abbey' version of the Royal Family."

She said its historical figures had been "wildly distorted for dramatic effect" and described the series as "cruel."

Royal biographer Penny Juror adds that the series is "very unfair on those it depicts."

'The Crown' season 4 is currently streaming on Netflix.
