I can’t be the only one who thinks YR was the first game when the RA series went off the deep-end into not-good-ness.

I think at that point GRRM never actually wrote the books for the last few seasons (fans are still waiting lol) but be might have said what he was going to do in those books to the TV show writers. But since it was never fleshed out, the TV show writers apparently decided to make the last few seasons “not fleshed out”. Or, they just weren’t capable of original writing that wasn’t copying the (allegedly good) source material.
