As I was watching it, I found it to be faithful to the story... though sometimes a little more nudity than I needed...
I wondered if those that hadn't read the books would be able to follow it. The casting was very good, though Ned, Robert and Catelyn are a little older than they should be - Cersei is about the right age.
I'm impatiently waiting for my husband to finish the new book so I can dig my fingers into it.
