George R.R. Martin’s Influence
Martin claimed that he didn’t like the direction that Game of Thrones went after they ran out of source material. This was partly his fault because he didn’t finish writing the books. However, the showrunners didn’t carry out his vision in the later stages because they wanted to complete the show.

Fortunately, this appears to be less of a difficulty with House of the Dragon. That’s because Martin says that he has more creative control over the new series. It’s good that the author and the producers are on the same page because it will make the fans happier too (via IGN).
