He was already worried about the course of the series.
The creator of the Game of Thrones series, George RR Martin, also touched on the controversial final seasons of the Game of Thrones series in an interview with The New York Times . He announced that he was “out of the show” after 4 seasons, especially since he hasn’t appeared at all in the last two seasons. In fact, the last two seasons of the series keep their place in the memories as the two seasons when things broke down.
Martin was involved in the show’s first four seasons, but he says he was completely out of business in seasons 5 and 6, and especially in seasons 7 and 8.
Martin answered the question asking him to explain the situation by saying, “Ask Dan and David about this.” The names he is talking about are DB Weiss and David Benioff, executives of Game of Thrones.
The 5th season of the series was the point where he started to break away from the novels, which are the source works, and then he drew a completely different path for himself.
Already after the 5th season, Martin said that he was worried about the way the series was going, and he started to say “they don’t follow my template”. While the first seasons progressed according to the roadmap drawn by George, serious deviations began with the fifth season.
Of course, George RR Martin will still be writing the new book and we’ll find out where it takes the story, don’t die donkey don’t die.
