I spent a bunch of time bitching about how much Show Stannis sucks, so let me just say the Walder Frey and Roose Bolton scene was a good reminder of the advantages of not having the book's PoV structure. The opening scene with the butchering of the northern army and Robb Stark with the direwolf head was great, too. And I was overjoyed that Guest Right was finally acknowledged. I was hoping for it before RW, but after works just fine, as long as its there.
