GoT was “torn to shreds” because it rushed the story, butchered the characters and the lore, put all the dumb memes on screen, and did so in 6 episodes that we had to wait a whole year for (back then we had a new season every year). And I blame GRRM as much as D&D. If he had written the books on time, D&D would have had more concrete material (they could have adapted The Vale and Lady Stoneheart, but I’m being generous).
