If you look close, its more than just "inaccuracies from the books, tis about they fucking up the book and making up their own garbage.
they could have said they were doing something original, unrelated to the books, more about a re-tealing, but they said, "now e are going to be faithful" "when he had doubts back to the book" wand it was a lot of horse shit.
They could have made a good fantasy show, but even at that they failed. If you completely ignore the lore changes, still is a bad show, with a bad protagonist, bad plot, poor dialogue and countless of other shit. Unlike the game that people found enjoyable even with the lore changed, that they didn't pretend it was faithful.
There is also the point that the show cost so much, with such big ip, and they made something like C tier netflix show.
