You will watch weak characters. Weak script. With a nice scenary and music (same of GoT). They want this second Daenerys support all the weight of the show, and it's impossible. The only character i admired a bit was Daemon, buuuuut when i finished chapter 2 i thought he was a coward. What a bluff...

That works the same for books in real life (i am not talking about got now). If your history (not talking about narrative style) is weak... and your characters are also weak...

Remember, the scenary (dragons, world, clothing) is good. So, they can try to cheat you. And also you can watch one or two decent scenes per chapter. But don't forget about characters and narration.
