That too. He was a complex character, constantly worried about having to protect his clan, his family and those he loves, while trying to pull his weight in their group, despite not having the same kind of magical abilities over elements that the others possessed.

Meanwhile, in Korra, nearly every character was either one-dimensional, or an anthropomorphised trope, or a plot device. Even Korra herself would conveniently forget she had abilities she'd displayed before, just because if she'd been competent and consistent, then the antagonists would have been defeated within minutes of their first encounters. She would fail or succeed challenges, not because it made sense narratively, but just because the plot demanded it.

It's hard to fathom that the same writer wrote on both shows, considering the vast difference in quality between the two.
