The graphics, casting, audio, and overall aesthetic are brilliantly done. That being said, while I understand obviously that a show will differ from the books, many of the changes take away a lot from the story and do not serve an obvious purpose. Every characters personality is warped to be more lame, more rude or obnoxious, or just forgettable.
It's obvious that they are jumping on the game of throne edge lord vibes for no obvious cause. It doesn't need to be GOT. They don't give the characters time to breathe or grow and overall I'm disappointed.
