7. The Night King Triumphant
Season 5, Episode 8: "Hardhome"
You want an anti-war metaphor? How about a literal avalanche of bloodthirsty corpses raining down on humanity? That was the fate that befell the isolated village of Hardhome in an out-of-nowhere attack by the White Walkers and their undead army on those who'd gathered there in a last-ditch attempt to get everyone out of harm's way. But the truly stunning moment came after the fighting stopped and the few survivors, including Jon Snow, started drifting away on their boats. The Walkers' leader, the Night King, raised his arms – and every man, woman, and child who'd just died rose again, ready to kill. Accompanied only by the sound of the waves, this face-off between good and evil was the series at its epic-fantasy best.
