I just did season three in one sitting. I didn't like it too much. It was a little slow and jumped around between too many characters. I guess seasons three and four are actually going to be the third book split in half, from what I've heard. And that makes sense since this season seemed like the start of a lot.
Not enough Whitewalkers either. Something tells me my desire to see more of that won't be fulfilled until season eight.
