That's basically what it is, except with less Middle Earth and more sexual violence, incest and pedophilia. At least the first couple of books are; I never bothered reading past the second book or watching the series.
It's because I pointed those things out. As far as I could tell GoT is primarily about feeding those pornographic desires whilst hiding behind a facade of medieval fantasy fiction.
I would have continued the series if I thought his writing were any good, in spite of the clearly repressed sexuality he was indulging himself in.
