Much simpler than GoT.

First few episodes are somewhat interesting, you start to pick your favorite characters, a few of them show some good qualities. Then after about episode 6 it all goes downhill.

The story: a bunch of depraved individuals kill or copulate with each other in order to be the next in line in the king's succession. Nothing else matters, nothing else is shown. Not a word on economy, philosophy, technology, social issues, context.

The setting: early medieval kind of society, some magic (dragons), knights, lords, sword fighting, dark castles.

The show is so monothematic that it's boring. Everybody is trying to be the next king/queen or be in their good graces. No context, no particular motivations for the characters. Even the current king himself doesn't look too happy or powerful or like he has accomplished anything of value other than just being the king. Hardly in a position to envy. Why then is everybody trying to be next?

The writers cater to those who like to see grotesque scenes, depravity, gore. I am not one of them. It is one thing to shock audiences every now and then to spice up the story but in this case the grotesque is the main dish. I find that very distasteful.

By the end of episode 8 there was nobody left for me to root for. I couldn't care less about who gets to be the next king/queen or even about who survives. The dragons could burn everybody up for all I cared.
