I'd like to answer this, because tbh I meant to respond to it. Or maybe not, given who originally said it.
On the one hand, yeah. They changed the dynamic between Jamie and Cercei. And they changed the initial dynamic between Drogo and Daenerys. One might question why. On the other hand, as far as Daenerys can go, I think you can throw out the consent altogether because a.) in the book, she's 13, and b.) she's not foolish/suicidal enough to say "no". It's an arranged-wedding night consummation between a big man and a kid. You're telling me that the crying is right out? Next question: if you think she's going to be enthusiastic, are you out of your fucking mind? Second question: what kind of sick person has given this much thought to a 13-year-old's wedding night?
On the other hand, well, it sure seems like people are focusing on two horrific things that resulted from story changes, in a series that's full of horrible things and horrible people. Crossbow bolt to the face? Meh. Belly full of steel? Snooze. Cleaving people in two? Oh, well. Giving people to the Drowned God? Hit the snooze button. Changing Cercei's and Jaimie's sex scene in the presence of their son's corpse from grudgingly consensual to not consensual at all? This is an outrage.
