I have been thinking of all the flaws/decline in plot scripts lately. I have criticised some of the stupid moves myself but If I am to think from producers point of view; I believe GRRM dicked them.
The show began in 2011 with just two books to be released. they must have planned for 10 or so seasons, thinking GRRM would finish both the books by then.
Whole TV series is about to end and GRRM is yet to release his next book.
I don’t think GRRM might have given them the liberty to work the story as they wish. He has his own interest to serve & wouldn’t want to have something better compete with his writing, although he is talented enough to not be scared of it.
Most likely the producers were forced to go down the simple route & hence shorter seasons & episodes.
I understand he has his own life but 7 years for one book whose plot is already laid out since 1998 is just poor show. GRRM has spoiled one of greatest TV show.
