I just finished the first season and just before that I have read the first two books. Now everything is fresh in my mind and I can compare apples vs apples. As a first season the show is quite enjoyable as an adaption to the books it felt more like the people writing the script did not read the book but was told of the book. The last few episodes completely ignored what happened in the book especially how the riles each character played.
As a show I will give it a good 7 for an adaption I will give it 3.
