A pretty solid finale...right up until the last scene. They blew it. Couldn't keep that annoying little runt Olly out of it, could you, D&D? Whose fucking idea was it to ever have that irritating little shit be a character in this? Did an HBO executive's kid really want a part or something? Ever since he showed up, he's just been eating up screen time, doing things that were reserved for other, better characters, and in general just being an all-around drag on the show. And now he gets to deliver the coup de grâce to Jon Snow. Also, even setting aside Olly's involvement, the whole scene came right the fuck out of nowhere. In the books, Jon pushed and provoked the Night's Watch repeatedly, testing their loyalty multiple times with a series of questionable decisions, and when he finally goes too far, they lash out at him almost spontaneously. Here, he does one thing that they don't like...so they wait several days before setting a bizarre trap for him, and coldly, dispassionately execute him once he falls for it. It doesn't feel earned at all.
D&D are apparently insisting that Stannis and Jon are really dead, too.
