I have to disagree with Yahtzee's defense of the GoT rape scene. Not because I have a problem with the scene, because I haven't seen the episode. But I don't think his argument in general holds water.
There are many storytelling devices that will always get an emotional reaction out of the viewer, regardless of how well told the story is. Killing an innocent dog, for example. Rape is one of those devices. You could have the most poorly written, 2-dimensional character ever, but if you show them being raped people will react strongly. In fact, many lazy artists will use rape for exactly this reason. As a result it's really hard to make a rape scene that doesn't feel exploitative or manipulative, because so many rape scenes are exploitative and manipulative. A rape scene getting a rise out of it's audience only means the audience is human, not that the scene was tasteful or worked in the story.
Also, I don't buy the argument that this is okay purely because GoT is a story where awful things constantly happen to the characters. GoT is more than that. Yes, it takes place in an incredibly harsh and unforgiving world, but it still tells an engaging character driven story. If it was just bad things happening to good people it wouldn't be nearly as popular.
