She was particularly critical of The Crown and its depiction of Royal Family: "I don't watch The Crown and I feel very protective about the Royal Family. They shouldn't have their life made into a soap opera as they're still living it."
Margolyes added: "I don't like seeing people's lives on TV who are still alive. I think that's quite wrong."
Though not a fan of The Crown, Margolyes did have praise for the BBC's historical drama Call the Midwife: "Call the Midwife is the number one show on British TV and it's not difficult to see why."
She continued: "The characters and the actors who play them are superb, the scripts outstanding. The success of the show is in the scripts and the producers take endless trouble with them. The scripts are truthful, and about real people and real things that happened."
The most recent season of The Crown has come under criticism for its lack of factual accuracy as it moves closer to the present day.
Season five takes place between 1991 and 1997 and includes events such as the divorce of Prince Charles and Princess Diana, Prince Philip's controversial relationship with Penelope Knatchbull and Tony Blair's landslide election win.
Several of those depicted in the show including Blair and his predecessor John Major have been critical of how the show depicted certain events.
He also called the scenes "fiction. Pure and simple."
