I may be wrong but I know for sure that Game of Thrones is the hottest TV series and since the final season has finally arrived, a high number of people are tuned into HBO like never before.
At the same time, some people, like the White Chicks actor Marlon Wayans is not into the series at all and he has his reasons.

TMZ caught up with him at LAX and while he was well aware that the new season has taken off, he called out the show for the lack of black actors...https://tarajmediahub.com/game-of-thrones-lack-black-actors-marlon-wayans

He is lucky the show writers considered having a few.
Back in medieval times black people were unheard of.
As a fantasy show a few black British actors made the roster selection.
Grey Worm and Missandei are what again?
They sure aren’t white people.
If he wants to raise an issue he should highlight the non inclusion of Asian characters.
