I know the show's never been about wrapping everything up in a satisfying way, but after trudging through seven seasons of barbed wire with our intestines hanging out, begging for anything nice to happen, would it really be too much to ask for the show to end with something resembling a triumphant victory?
On The Other Hand ...
Game Of Thrones has never been about "giving fans what they want." In fact, not only is it very deliberately the opposite of that, that's also PRECISELY why we love it. If all the show did was portray virtuous, likable characters triumphing over wormy cowards, then we'd just be watching some fairy tale from the '50s that would've lost our interest four seasons and a dozen unambiguous Jon Snow triumphs ago.
Victories that he would almost definitely frown through.
Ending the show with Jon and Samwell Tarly high-fiving and going "Ya did it, champ!" "No ... WE did it ...," followed by swelling orchestral music and a quick cut of all the Seven Kingdoms celebrating would be the biggest pulled punch in the history of fiction. Do we really want that?
