TL;DR don't waste your time.

I seriously don't understand how did this show get such a high rating (8.5 currently). I literally opened an account here just to normalize the rating a bit.

Vast amount of long scenes in which absolutely nothing happens. Long conversations of little or no importance to the story: "Your grace. May I have a word? Lord Commander, please. My queen, how is your grandsire. Fine, how are you?" etc. Characters who are almost instantly forgettable. Main characters with unclear motives...

It's as if someone wanted to tell you a story which spans over 10 decades, but emphasized only the least important aspects. In the end you're stuck listening to the person for 10 hours, learning nothing, expecting "something" to happen, only for the person to tell you: "You know what. Now that I actually came to somewhat of an interesting point, I'm just gonna wrap it up here and leave you hanging for some time". That's how I felt after the last episode - left alone after having 10 hours of my life literally wasted.

I gave it 3/10 just for the first 3 episodes - those were actually interesting. The rest was a serious waste of time.
