There are, as I recall, three really gory scenes (more like shots), and an additional one involving animal cruelty. If you read the books, you probably know at least one of the scenes for people & the animal one. There are also a couple of gratuitous scatological opening scenes featuring males.

The most troubling, IMO, is a scene where they are extensively discussing an act of sodomy (by which I mean extreme freak sex, not gay stuff), and one of the actors participating in the discussion is a nine year old child. They actually made a young boy talk about gross sexual acts, for no really necessary reason. I mean, we thought it was bad when they added in a rape scene for Sansa & a sex scene for Arya, where the producers did this, on their own, involving actors they had known since they were children, but at least Turner & Williams were adults when the scenes were filmed. The kid in Kot7K was only nine at the time. This is a hair away from grooming & pedo service.

That being said, without the gratuitous stuff I mentioned, it's pretty good, with my major complaint being the excision of the climactic thematic scene of the whole story. But they still service the theme pretty good and it's the sole show in the whole franchise to actually address the more hopeful & idealistic message of the overall story (I maintain that aSoI&F is not nearly as cynical or nihilistic as the show or many interpretations of the series, and a better description would be "informed romantic." The tagline should not be "win or die" but something like "yeah life sucks, but keep trying. It's important, even if you don't get how." Or as Dunk would say, you never know when the realm will need a hedge knight's hand & foot.
