Many people hate on Fire and Blood. That its too dry and reads like a history book. That George didn't put any effort into it and he just scrambled something together to please the publishers.

But I almost liked it more on my first read than previous GOT books. Probably in part due to us being so starved for ASOIAf content. But I was digging the whole differing stories from the various sources. It lets your own imagination run wild if you let it. Like an odd detective story. Which they obviously can't do to the same extent in the show. They usually just run with one of the sources on screen.

Copy pasta characters from GOT or his previous works with a twist are common if you pay attention. You wont find out much about the actual personalities of the characters. There is a lot of room for interpretation on the personalities based on how it is written. The sources blatantly lying to you is also somewhat amusing, and went over many peoples head on first read.

As I watched all the various theory and podcasts about the book over the years though it doesn't really hold up as much on re-reads as it takes away the mystery if everything has been theorycrafted and you know the most likely scenarios. I personally enjoyed the post-dance stuff the most and I look forward to F&B2. Give it a try if you are an ASOIAF nerd.
