Finished Storm of Swords.
I would rate it a 4.7 out of 5 compared to 5 out of 5 for the first two books with a great many 6 out of 5 moments.
Storm of Swords has 3 of the biggest events from the show (Red and Purple Weddings, Trial). It ends with massive cliffhangers.
However there are a few parts that aren't that good and drag a bit. Also the character development and plot is moving too slowly at times. So the experience is not as fluid as the first two books at times. I still have the sense that GRRM is awesome at world building and creating a lot of new and interesting characters. However the depth of the characters aren't as deep as they could be. The psychological progression is too simple or even nonexistent. There are also more scenarios that are more and more contrived for shock value and seemingly for the sake of cutting off loose ends- like all of Littlefinger-Sansa-Lysa stuff and 4 deaths that cut short 3 highly developed characters and 1 really promising character.
