Here's my very basic breakdown of how I feel in terms of books to movies.
Book 1, very good book, with the season being remarkably close to the source material.
Book 2, okay book with great moments but at times extremely boring, season 2 veers quite a bit at times, almost always for the better.
Book 3, fucking amazing, top to bottom. Seasons 3 and 4 have veered quite a bit, but mostly to good results (not always an improvement, but still pretty good -- I feel there is a lot of "works in the book, wouldn't work on the show" moments.
Book 4, underrated book, already making appearances this season. Super curious to see what next season is like melding this book and book 5.
Book 5 I really struggled to get through, so I'm curious what a reread will do for me.
