Unfortunately I disagree with most people it seems! The bar GOT set has been so high it was almost impossible to maintain. Sadly one of the the mistake was to try be a second GOT. Meanwhile the creators thought that what was so exceptional for GOT was the terrible violence and sex. This is forgetting about the incredible writing behind the series. Tyrion sense of humour and self dérision was an almost onetime thing. The development of characters was also rich and never one sided- very complex as human beings are.
So it is not a continuation of GOT. Despite the decor, the clothing, the dragons it should be seen on its own. Not a bad show but will never reach the quality of GOT (of course except the awful last episode).
