It will take another decade or so for most to agree on this but it will happen.
For the Hobbit though, this will never happen, most of those movies were garbage.
For that matter, the first few Harry Potter movies are better than their respective books, though for the last few this swaps and the books are better.
Game of Thrones/Ice and Fire book 4 and 5 are WORSE than the show...and objectively even beyond that the show is better (even if it's hot trash) because it at least exists and will ever exist.
I would have preferred them to actually have kept the show exactly like the books. It's HBO they could have afforded it. ---
