I agree, after building up the Night King as a threat for more than 7 seasons now, this battle needed to be more impactful and the victory to come at more of a cost. And I'm surprised at how linear this season is so far. Three episodes to build to fighting Night King, defeat him, now on to Cersei. I expected more to be going on at the same time. A three way fight over the penultimate couple of episodes would have been pretty incredible.
