It makes me wonder why didn't the creators take on the far more logical tale of how the Targaryen's come to Westeros and captured it. What machinations were used and what allies were made to make it work.

Instead we get this storyline. It isn't always comprehensible and is definitely not very intriguing, but you get more of the story of how the platinum blondes managed to have such a broad base that it included black ones and how desperately they wanted to have women assume their role as equals (only to need to lose it later since they won't have it in the later stories) and more pointless drivil.

A great family (perhaps the first rulers of Dorne would have been more logical for a great house which was black, It could have been shown as more courageously a house fought for and managed to remain a kingdom until the end (perhaps even with the family that cut the successful deal being the House of MarteL).

But no! We get this very poor tale of a very weak king.
