I'm appalled. Even if the show producers were forced to portray siblings' sex as something negative, they didn't have to do
that. Jamie and Cersei already ****ed by Joffrey's dead body which, I thought, conveyed a quite obvious message. No need to add rape to that. Especially since Jamie would never.
They did the same thing with Dany's 1st time with Drogo. In the book she was thirsty af and in the show they made her cry. Like

It's obvious sexism, but I don't have the strength to be angered by this anymore.
