Ok. It's early so all of the first reviews coming in will be from a lot of fanboys and will be very inflated. Here's the truth.

Cons: The casting is awful.

The script is forced and rushed.

The acting is subpar.

The character development is mediocre at best, it has a very United Nations vibe, very much trying to cast all races just for the sake of it.

It's gorey for the sake of being gorey. The nude scenes also aren't well done, very rushed.

Pros: Music is well done.

Set locations are again very well done in keeping with the GoT themes, they obviously spent a ton of money here in set production.

I'm hopeful but not optimistic. I'll keep watching for a few more episodes but so far this first episode was horrid except for the final 10 mins, but, it wasn't enough to clear the bad taste out of my mouth. So far this series has a vibe of "throw tons of money at it and everything should be fine". But it's not.
