Shingeki no Kyojin came and went, its main bulk plenty of years ago, but as I was thinking of worldbuilding earlier, this story’s popped into my mind. There aren’t many worlds as strange, compelling, tension-filled, yet internally coherent as that one. I have my issues with the ending (I think Isayama should have gone the whole way), but most of the series remains amazing, a hard-to-compare classic of modern fiction.
And those openings from the near-perfect first two seasons. Gave me chills all over again.
