That's how I felt after episode 9. The Starks were the family to go for, and now all the grown one's are dead besides Snow.
That's what I'm hoping for too, for Snow to go beast mode on the Lanisters.
Picked up the book at the airport a couple weeks back, so far so good. I think a movie could have been done the way the book is written, but I can still see why they didn't go that route. Still will definitely see it though, love zombie movies.
