I recently was re-watching some of GoT, because apparently I like to torture myself, and was struck by how vapid the dialogue was. I went to see who wrote the episode and sure enough. Then I looked at the episodes that were submitted by the showrunners for writing Emmys. They all were written by you guessed who. Those pompous asses didn't even let GRRM win an Emmy for, say, Battle of the Blackwater, while they collected awards for adapting his work. I wonder if that sort of thing is why GRRM distanced himself from the production in latter years.
