Two prominent Hollywood figures blasted the hit HBO fantasy series “Game of Thrones” over its treatment of the female characters on the show.

Actress Jessica Chastain “criticized the show for using the rape and torture that Sophie Turner’s character, Sansa Stark, endured in previous seasons as the reasons for her strength and cunning,” Variety reports.

Chastain let her feelings be known in a tweet sent out following Sunday’s episode, writing: “Rape is not a tool to make a character stronger. A woman doesn’t need to be victimized in order to become a butterfly. The #littlebird was always a Phoenix. Her prevailing strength is solely because of her. And her alone.”

Variety notes that Turner plays the “Dark Phoenix” in Disney-Fox’s upcoming “X-Men” film, which co-stars Chastain.

“Some ‘Thrones’ fans believe the lack of female writers and directors led to the unsatisfying depiction of Sansa as a survivor of sexual assault,” Variety notes. “In the entire run of HBO’s series, only one female director has been brought on, Michelle MacLaren, who helmed four episodes, the last of which was in 2014. Jane Espenson, Vanessa Taylor and Gursimran Sandhu are the only female writers, contributing to nine episodes total.”

Also voicing dissatisfaction with the show was director Ava DuVernay, who (SPOILER ALERT) lamented the treatment of the only woman of color on the show.

“So… the one and only sister on the whole epic, years-long series? That’s what you wanna do? Okay,” DuVernay tweeted after the objectification and shocking death of Missandei.
