Don’t get me wrong. I love that show. Yes, the Red Wedding was gruesome and shocking. Do you have any idea how many millions of people were murdered in World War Two? Dragons raining fire and death from the sky. We dropped bombs on Germany and Japan that wiped out cities and started fire storms, and we dropped even more bombs on Vietnam than all the bombs dropped by all the planes of all the forces in World War Two. Napalm and Nukes might just put dragon fire to shame. The Lannister incest was controversial, in a small way, but for most of the last 1,000 years or so, most of European royalty has been marrying their own cousins. That is how Prince Charles got those goofy ears. Inbreeding.
All I am saying is, if knights and swords and brutal battles and steamy love scenes interest you in fiction, read some history. Listen to some historical books. It is all in there.
