There isn't anything in season 8 that properly fits the narratives established in the previous seasons. But its greatest flaw is how it fails character development. Developing character also means being true to character. Thomas Hardy showed that in his novels, when his chief characters were inevitably undone by their flaws they were unable to escape. Two examples in the GofT: John Snow remains as cardboard and as unevolved as he was in the earlier seasons, and even more than that, he shows time and again that he is clearly the dimmest one in the room. It is scarcely credible that anyone might think he could rule a schoolyard let alone ascend to the Iron Throne, particularly when he consistently refuses to lead when offered the role. Whenever he is required to lead he is as brainless as a chook. He reads no one and no situation accurately. He is a creature of impulse, not intellect. The one true thing about John Snow is that he truly "knows nothing". Tyrion, on the other hand, who was once the sharpest tool in the kit in his cynical earlier days, now rivals Snow for sheer denseness since he has become the naively idealistic Hand of the Queen. He makes mistake after mistake, but his worst blunder is how he sells out his friend and ally Lord Varys. The idiot Snow tells his family who he really is, that he is the true surviving heir to the Iron Throne, while protesting he doesn't want it - so why tell them? - and then of course Sansa tells Tyrion who then tells Lord Varys, who remarks that it is therefore "no longer a secret but information". Tyrion might as well have blasted the news from the roof tops. But when Lord Varys suggests that Snow might have a better claim to rule than an increasingly mad queen - now proven - Tyrion informs on him to the Queen, which sees his old friend - yeah, right - immolated by the Queen and her remaining dragon. Such is friendship. But once again it is Tyrion's improbable stupidity - in the light of his character's earlier development - that costs his friend's life. Did I mention that Tyrion is also an informer? There isn't a character who, in season 8, has survived the ineptitude of the series' writers. Explosions, which are many in these later episodes, are an apt metaphor for what has happened to the series. It is a bomb.
