« The thing that bugged me the most about the Night Kings death is not so much how it happened its when it happened. I haven’t read the books but the impression i got from watching the show was that you have all these rulers fighting over the throne with the petty bickering and back stabbing. And while all this is going on the real threat to everyone is the mysterious Night King and the white walkers. But, by not having the Night King as the final boss of the show they’re basically saying…nah the show actually is just about fighting over the throne, the Night King and the white walkers was just some under developed side plot that was fairly easily resolved and was ultimately unnecessary the overall plot of the show. If I was to pick out one thing I hated most about the final season it would be this because it retroactively ruins your whole perception of the series right from scene 1 of the show.»
I found this quote on a YouTube video, and found it to perfectly sum up my feelings on why I feel the need to end my GoT franchise on a very dark ending with the Night King winning.
