The first season was a great adaptation that honoured the source material and added some new, interesting plot. The second season, other than the first episode, is almost unrecognisable. This wouldn't be a problem if the changes were good but some episodes are so poorly written, they feel like a cheap parody. The final two episodes were very well done but didnt quite make up for the slog that was episodes 2 - 6. There was another dip in quality in the third season. It was 8 episodes of nothing. The writers took some of the best scenes from the books and somehow made them incredibly boring.

I've updated my review after each season. I don't plan to watch the fourth season. My recommendation is watch the first season, then move on.

Season 1: 9/10 Season 2: 6/10.

Season 3: 4/10.
