It's ok, but being the same style in almost every aspect as Game of Thrones, it appeals mostly to hard core fans. I would have liked it to be different i.e. Not repeat the same topics (incest, gore, dragons...), but I understand it couldn't, being in the same fantasy world. George is a great writer and great writers can be also versatile, meaning they would be able to switch style without much loss in quality. That being said, and me being a GOT fan, I like it because it brings back that world which I have missed. I would have also preferred that Milly Alcock would continue being Rhaenyra, not that Emma D'Arcy isn't good, she is a great actress, but the switch is jarring. I also don't know where they intend to go with the show, if it follows exactly the original (history) book it is based on, it will span many centuries and therefore there would be a risk of dilution - being attached to the characters/actors in a series is an essential ingredient for its success with viewers, not having that is a risk of the viewers giving up too early on it, after their beloved characters leave the show (creators have certainly known that and read the many psychology articles describing the phenomenon, so I hope they would be careful).
