(Game of Thrones and Walking Dead comics)I was talking about the actual world building aspects of Game of Thrones, and not the fantastical plot points like dragons, ice monsters, etc. The show has cut out all sorts of colorful and unique characters from the books and replaced them with more "realistic" characters, the same way that The Walking Dead has done in the past (The Governor). If HBO cut/changed Vargo Hoat, I don't see why they wouldn't also do the same with Negan, who is, by far, the more over the top character.
I mentioned this a couple days ago, but HBO has trouble putting CG-enlarged dogs (Direwolves) on screen next to their actors and have drastically reduced their screen time and importance to the plot even though they're a major part of the books. Being on HBO wouldn't guarantee The Walking Dead a tiger, just as being on AMC doesn't guarantee there won't be.
GOT Spoilers
re:direwolves isn't really a good example seeing as Sansa's is dead, Rob's is dead, Arya's is missing, Bran is out of book material, Rickon is missing, and Ghost I can give you that but they even shoehorned him into that scene with Sam which wasn't in the books. And you really can't argue there is a lack of CGI on GOT after watching ep8 and 9 last season... I don't recall seeing that level of detailed CGI ever in a show before
