I really don't know what to say, other than IT'S LONG. It might be my least favorite of the five, and my dislike for it is compounded by the fact that I had to wait FOREVER for it to be published. To me, it left like they cut parts out of A Feast For Crows that didn't advance the plot and just shoved them into A Dance With Dragons.
In short: NOTHING HAPPENS.
For a book titled "Dance With Dragons", I actually expected the dragons in the book to - I don't know - DO SHIT. Instead, I get Bran turning into an omnipotent tree.
I know that George R. R. Martin is not my bitch (shout out to Neil Gaiman...yo!), but the dude better put his editing of compilation novels aside and churn out the next book as soon as possible to held get rid of the bad taste this one left me...
