My wife has read the books, and she has said 1000 times in two seasons “that’s not in the books.” I’m not a fiction reader, so I can’t tell when a movie goes astray of “canon” from the books, and I think I enjoy the adaptations more because of it. Were I to read and enjoy the books, I doubt I’d watch the movies… no way can a tv series not guaranteed to be produced year to year is going to stick to chronology, characters, or anything more than general theme. That’s not to mention matching the imaginations of the reader.
Seems a doomed proposition to me. While some might do better than others, it’ll never match a well written book coming alive in your mind.
I’m enjoying parts of it, while some characters are very wearing to slog through. I’ve certainly seen worse. Season two is much less focused than the first.
