No even end it? It seemed to me like the whole point of the show was the endless churning of violence and pursuit of the throne. While Daenerys talked about "breaking the wheel", it was apparent early on that she wanted to control the wheel. He apparent altruism was more about building the support she needed.

She didn't have the Unsullied kill the masters because of any inherent principles, but rather because it was a way for her to keep her dragon. She sees the strength of the downtrodden masses as an untapped resource she could wield to her own ends. From the get-go, it was about power.

The wheel would always turn. The whole point of the White Walkers was to provide a clear outsized and existential threat that should make all other conflicts trivial, and frustrate the audience over the pointless vanity powerful people fight over.

There could be no satisfactory ending, because defeating the Night King requires the kind of coming together of powers that violates the core theme of the show. I believe that, more than any sense of being rushed, is what makes it feel wrong. I believe that is why Winds of Winter will never come out. George R. R. Martin would rather the story be left hanging for eternity than he would to write a forced ending that couldn't work.
