Look, if the rape scene was absolutely necessary to further the story, so be it. We'll see whether it was depending on what happens next. If, for example, Sansa and/or Theon immediately get revenge, then the rape scene wasn't necessary, because that revenge was easily justified and could have easily happened before it.
But the worst part was how the rape scene exemplified the worst trope about rape - the real victim wasn't even allowed to own the victimization. Instead of the scene focusing on Sansa and how awful of a situation Sansa was in, the camera instead focused on Theon and portrayed Theon as the real victim of Sansa's rape.
Not that I'd alternatively have Sansa actually be on screen during it, but it would have at least been better if the scene allowed Sansa to be the primary victim in some way - perhaps a quick cut to black without showing any of it and letting it stay implied or show just the moments after it happened. Pretty much anything could have been better.
That's what bothers me most about the sequence. Sure, whatever, Sansa needed to be raped in order for the scene to be "realistic" in the world and perhaps further the story. But she didn't even get to fully own the victimization of that action.
I'm seriously trying to picture someone casually watching the show on a sunday night and suddenly jumping to their feet and shaking their fist screaming "She didn't even get to own her own victimization!!!"
It was unnecessary.
We knew they would have sex. They're getting married. We can assume that he would be cruel about it because oh, wow, he's Ramsay Bolton and he's godawful. Would Sansa enjoy it? No. That's obvious. So the scene teaches us absolutely nothing new. It's as obvious as the fact that the characters wake, get dressed, eat, and then go about their day. So predictable, it is mundane.
Even of we had to have this explained to us, they could have done it the morning after through dialogue with more opportunity for character development rather than a drawn out conversation about what we all knew was coming and ominous music and gratuitous sounds of her suffering. We could have even seen how she was going to leverage this or how she reacted or how Reek reacted or Ramsay's former flame or Roose. But, as with everything else this season, leave it to another episode.
Are you serious? Morning after dialogue?
