The production value of the show is unquestionably awesome, however a good looking show is not the same as a good show.
If you read the books your going to be yelling at the screen about why they removed key parts of the story just to waste time on embellishments on trivial thing or down right inventing scenes. If the story is to big you have to cut primary characters and events out dont go back and add things that never happened.
If you haven't read the books your going to be lost as they don't take the time to properly build up the story and back ground of the characters they do add and why they are motivated by what they do. And scenes will jump way to far and too fast.
