Even I am slightly surprised at just how unhappy it's going to be though. I always thought the Fat Fuck's 'bittersweet' ending meant that either the 'goodies' beat the Night King, but then the baddies took over (so Jon and Danenerys are heroes but then Cersei kills them) or that the 'goodies' die while beating the baddies, or one goody has to sacrifice another goody to beat the baddies. Still some hope for humanity in the darkness.Yeah , somehow a coffee cup made it past the actors, director, props, editing, vfx and everybody else that was involved.
Kings landing is going to be a massacre, there is no happy ending here. Every faction are going to look like a bunch of cunts.
But as you say, they're all going to be a bunch of cunts. It's not 'bittersweet' - it's just bitter.
Sansa is going to be the last one standing and she's ultimately the main character of the story. It's the story of an abuse victim just continuing the cycle of abuse, mistrust, jealously and hatred. Which makes a lot of sense and I give them props for that.
