This show is definitely not in the same category as Game of Thrones. There's no rythm, no humour or wit, very little is happening, too many long dialogues or monologues that would like to be shakespearian, the cast is not as charismatic as the GOT was from the start. If you want actual shakespearian script and dialogues , go for the real thing.

If you miss Game of Thrones, you'll be better off re-watching the original series, or reading the books.
