The Crown is deemed 'less disciplined' and 'unfocused' days before its release.
The Netflix series have been branded its “its weakest outing yet" in a swipe byDaniel D’Addario.
He continued: “A generally scattered and unfocused show is less disciplined than ever.”
Speaking about the Queen’s annus horribilis Christmas broadcast, Mr D’Addario added: “The real speech is online. No such grateful mention of her family, in those terms or any other, exists.
“This is not unethical, exactly – The Crown is not fact and does not present itself as such – but it’s an overreach that gives the game away.”
Meanwhile, actress Elizabeth Debicki, who plays Princess Diana, argued: “It is clearly fictional. I feel like audiences know that, because there are actors, playing parts.
“I never watched The Crown and thought, ‘This is a documentary’ or ‘This is obviously true’.”
In another swipe by PM Tony Blair, the show scene have been branded “complete and utter rubbish”.
