A disenfranchised/wronged female with dragons will fight for what is her right. I can see where this is going with the Hand's daughter marrying the King and having a boy child with him. Then dynastic war between Daughter 1 from Wife 1 and Son 2 from Wife 2.
Also far, far too graphic for me. Between the Tourney and the Caesarian, I had to close my eyes.
But I did like the dragons and the CGI Kings Landing.
I wish that the thousands of years prequel about the creation of the Others had had a good pilot and been the show we were watching. It would have been better I think. This is too close to the original story and is falling into the Star Wars trap.
