Yeah, interested to see how House of the Dragon goes. All of the source material is there from Fire and Blood, but adapting it into a tv show will be a challenge. The book is written as if it was a history book, citing in particular two really unreliable sources who had biases or exaggerated, so there's very very little dialogue bar bits of pieces and also the show will have to show these things that were left intentionally ambiguous in the book (why did person x do y, what become of this person, what did these two people say when they met)
I'm still hugely into ASOIAF so will give it a watch. How good it is will probably come down to how much they're willing to commit to the dragon fights. If they half ass the budget it will suck. Early image leaks made stuff like the wigs absolutely suck, but they can probably fix that quickly. The cast members I do know (Cooke, Smith and Considine), I quite like.
Book is worth a read or listen as well.
Edit: I also wonder how they're going to sidestep the fact that GRRM called two characters in the dance Kermit and Elmo....
