Yesterday I finished Clash of Kings and I have to say that the story has diverged pretty siginficantly from the HBO series. This IMO is not so bad as I somewhat like a lot of what they do in the TV series better than in the book. Also I feel that reading the rest of the books won't ruin my excitement I feel when anticipating new shows in the future.
So for those of you have have read the books and seen the TV series what do you think about the differences? Which story do you like better? To me they captured the general story and the essence of the books which is more to be said for most of the crap that you see on TV and film.
Also, I have noticed that A Feast for Crows and A Dance with Dragons get significantly more negative reviews on Amazon. Does the series really go downhill after A Storm of Swords (which I am starting to read right now)?
