Season Four is not anywhere near as good as the first three. Roger is a total miscast and at best they need to re-cast Ian to age him. They would be better served sticking to the books. I know you can not put all the material in they are long but they are making things up that add nothing and there is not nearly the level of action and intrigue as the books carried on. Stay closer to the authors story/vision and really think about your casting Roger is a total mistake.
