Good. Unless they wanted to do some corny "a new widling threat emerges" shyt I'm not sure there was anything to do. They already fukked up the Night King/Others but bringing back a similar threat wouldn't work, assuming this show would largely stick to the north. If Jon and company beat back the threat without the king or great houses getting involved what's the point.
The idea that these threats return is certainly valid but we're talking hundreds of years. I like the idea that the ASOIAF world is perpetually stuck in a technological dead end, because winter keeps destroying and rebuilding societies. And every 1000 years or so the Others return, Azor Ahai/Prince That Was Promised/The Last Hero/etc emerges with a magical sword to save the day. And then history is just retold and the stories become myths. So 1000 years from now, people might think Jon Snow was a man with a wolf's head. Or that Jamie Lannister was made of gold.
