Despite the lack of action, it was still a good episode. After all, you can’t have a war with each installment. Still, I would have Daemon or Rhaenyra sit on the Iron Throne any day over Viserys. And any episode with dragons is awesome.
I liked how the world was consistent with that of GoT, from the costumes to the characters. Knowing that these events transpired before the Long Night truly adds a new layer of appreciation for GoT. It was also bittersweet because House of the Dragon very clearly underscored the importance of the role of the Targaryens in the prophecy, none that really materialized in the end of Game of Thrones because showrunners were too busy wrapping things up to work on their Star Wars deal with Disney.
