A lot of good writing in there and some particularly fine character work but did anyone else feel like they were spinning their wheels? Especially in the last two books, "A Feast for Crows" and "A Dance with Dragons." I just read over 2,000 pages and various characters did a lot of things but very little seemed to move the main story forward. And it will be at least a year or more until the next book. I can barely keep track of his hundreds of characters and plot threads as it is. I'm sure in a year I'll have forgotten more than half.
Y'know, I read something by George R.R. Martin back in the seventies, serialized in Analog Magazine as "After the Festival" (I believe it was published in book form as "Dying of the Light.") I remember that it was a great story once it finally got moving but the first 2/3 had a lot of political back and forth that seemed to move very little. Maybe now that he's 5/7 of the way through his story (unless he goes from 7 to 8 or 9 volumes) the story will start to move forward.
