Everybody is hating on D&D, but GRRM is the culprit for this epic fiasco.

These guys never imagined when they started working on the TV show that GRRM would sit on his fat ass and stop writing. Winds of Winter should have been out by the time Season 3 aired and then GRRM would have had another 3 years to write the last book.

D&D were doing great when they only had to adapt the books into a TV show, which is itself already a monumental task. Then GRRM abandoned his project and left them with nothing to adapt. They basically had to complete his story and I'm sure this isn't what they wanted from the start.

Everybody is talking as if GRRM grew apart from D&D because he didn't like how the show turned, but it's all his fault for not doing his part and leaving these guys completely on their own.
