"[...] many of the criticisms of The Legend of Korra boil down to criticisms of Korra, and how she’s different from Aang." I have literally never heard anyone say this.

This seems like a very strange way of looking at media. Why does it even matter that Korra is important? The events didn't actually happen, who cares?

Then the article goes on to talk about the themes of both of the shows, but it doesn't lead to any conclusion, nor does it talk about how well the themes were executed. Just strange.
