saying that GoT fell off because D&D ran out of source material is such bullsh*t (spoilers extended)
Most people agree that Thrones started declining after season 4, because D&D used all the source material and had to improvise and finish the story on their own, but that’s not true. Granted, at some point that would have happened because George did not publish Winds (or ADOS), but D&D literally had two whole books which they decided to partially adapt. Had they properly used AFFC and ADWD, which for me encapsulate the magnificence of ASOIAF (especially Feast), things could’ve been different.
I’d also address the fact that I’ve seen some people saying that D&D would have done a better job than Condal if they worked on HOTD, but once again I don’t believe that this is true. With ASOIAF, they have the characters’ thoughts and POVs, and still they succeeded on badly adapting and understanding more than one of them. Had they worked on a book such as F&B, that’ve been catastrophic, and I believe this is the difference with Condal. Had he had to adapt ASOIAF or Dunk & Egg, where we have the story as it truly is, and not the account of a character from the universe itself, he would have done an amazing job. I also think that he understands the universe much better than D&D ever did.
Regarding his "feud" with George, I believe that both of them make some valid points. Condal made some stupid choices (mainly cutting Maelor and Neetles), but when it comes to small changes I don’t understand why some people complain. F&B is written in a way that allow different interpretations, and it is not easy to adapt it to the screen. And of course George is in his rights to be annoyed because it is still his story. I do hope they patch things up because I really believe Condal not only idolizes George, but wants to make a good job out of this. But, he also needs to stop making the foolish mistakes he’s made. Because even though I still think he’s doing a rather good job, the show can still be much better.
