While she didn't reveal whether she herself thought the show should have ended differently, she did say that everyone is entitled to their own opinion.
“Everyone is going to have their own opinion and they’re fully entitled to them. It’s art and it’s to be dissected and taken on in whatever individual way you wish,” she said. “And if you’re sad that the show is done and you’re sad because you enjoyed watching it, then that’s sad. It sucks this wasn’t the perfect ending that people were hoping for, but I truly believe we would never have made everyone happy.”
Lena Headey, who played Cersei Lannister, was a bit more forthcoming about her opinion on the finale back in July, telling The Guardian: “I invested as a viewer, and I have my favourite characters. And I’ve got a few of my own gripes. But I haven’t sat down drunkenly with [showrunners] David [Benioff] and Dan [Weiss] yet.”
“I will say I wanted a better death," she continued. “Obviously you dream of your death. You could go in any way on that show. So I was kind of gutted. But I just think they couldn’t have pleased everyone. No matter what they did, I think there was going to be some big comedown from the climb.”
