It's not as good as Game of Thrones at its height (Season 1-3), mainly because the characters and story are just less interesting and exciting. The scenario is much more calm in this series, being that the family that we follow are established and uncontested rulers, unlike the volatile situation of the original Game of Thrones, which created so many intrigues, betrayals, and wars.

That said, it's still an 8/10 show. The production values are quality and through the roof, unlike Amazon's Rings of power (where Amazon fumbled the ball badly). HBO took this show seriously and did not just make an aftershow of the original one.

You have the same quality atmosphere, cities, props, costumes, as the original show. In fact it is probably better than the later seasons of GOT.

Plus, the show is overall enjoyable especially for those of us that find themselves entertained by the Blonde Scandinavian like Targaryen dynasty (and I imagine many of us love this House and are sold on the show just for that alone, and Dragons).

Truth be told, let's just be honest and say that House Targaryen + Dragons + more Game of Thrones is an immediate minimum 8/10. Thank you HBO. In this boring world full of Amazon and Disney low value, this is a breath of fresh air.
