I remember when ADWD came out we talked about the books. I'm in the same boat as you. I've been very nitpicky about this season and it's frustrated me quite a bit. There is still some hope left as there are 2 80-minute episodes but from the way the first 4 went, I'm worried this show has gone the way of Dexter.
On the plus side, this season has actually made me hope GRRM actually finishes the books because I need his view of the ending.
