Euhm just to clarify in the medieval times and even in the ancient period people did not went on a raping spree in villages or killing babies for the fun of it. that's all Hollywood hyping up stuff. The same goes for the series ROME. 99% is all Hollywood speculation and is not supported by the facts and evidence.
Personally I find that game of thrones has an unusual amount of XXX and violence in them. For me its a lack of creativity on the part of script writers. I find the unusual amount of XXX a bit lowbrow and vulgar. That is why I do not watch the series anymore because you can sum it up like this: someone throws a little tantrum, gets mad, rapes women, bashes some dudes skull in gets happy and then ... gets splattered himself. Its stupid and hilarious how the repetitiveness is drooping down from this show.
