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.
