The House of the Dragons. Is a good start to a what can be a Incredible Show. For what I would do if I was a Producer/filmmaker.

I would continue making episodes until the time period of The Game of Thrones time period. Then remake/redo The Game of Thrones series.

Then I would make another series called "West of Westerrous" staring Aerria Stark. Because in the last season of The Game of Thrones. Season 8 episode 6. Aerria Stark tells John Snow she was going to explore what ever West of Westerrous and from there the Producers/Writers can continue with either the same story line as The Game of Thrones or make a new story line starring Aerria Stark (the girl who played Aerria Stark)
