I think we also have to ask - free-TV or cable adaptation? TV is going to want conisstent length episodes to fit in their grid. Chase was very happy with the Sopranos flexibility, he could hand one over to HBO that was 55 minutes, or 62, or 57, whatever. Film, cut, then time it so you could tell how long it was.
Until they actually put a number to it, and that was later in the series, I didn't picture Harry as THAT tall. Six four, five? Maybe. The one, two, five percenters. But six NINE gets noticed and mentioned. That's the how many in a thousand. The Wolfe mention shows the issue with numbers. I think the original is "a seventh of a ton" which is not usually good, but hardly disabling in most cases. Heck, Michael and Sanya are likely in the ballpark, and Hendricks more, though they are taller. I picture them in the 6'5", 6'6" area, though I think we are told Hendricks was 300 or more. Heck, my image of Michael was close to Merlin Olsen, and he played at 300 at times.
I think there is going to be an issue with religious ties. They are heavily linked with one brand of Christianity, which will turn some off some other Christians. Non Christians may be turned off. Athiests. The 30 piece of silver Denarians. The noose.
And so many characters... plenty will get dropped. Who's The Dresden Tom Bombadil?
As far as the sex.. Thomas is not raping his way thru Chicago. it's willing partners. Thomas is gorgeous. We keep hearing that. Think a Margot Robbie can't get some any evening she wants in the clubs?
Incest in the White Court? Um, Game of Thrones? Cercei and Jamie? Two of the main characters are brother and sister in bed in the first episode? With three kids? And some would read the whole powderkeg was sparked when a married prince ran away with the fiancee of another noble. consentual or not.
and what happens if Jim has not finished the series when the adaptation catches up? Holy G R R Martin, Batman! I want Jim writing the BAT, not some dude at HBO or Netflix. Heck, Martin never even told us for sure who Jon Snow's parents are....
