If you like to watch family politics with very little action or substance, this is the show for you.
It's hard to keep focus, especially since they based 70% of the series in the castle and you don't get to see the world like we did on GoT.
They used same style intro as GoT and the costumes felt familiar, but that's as far as it goes unfortunately.
It had a few really good Dragon fights in it, so that must be most of their budget and you can tell.
