I saw something about how people are confused bc Aang completed the elements and learned energy bending in one year, yet people don't bat an eye. Korra took about 17 years, and people call her a Mary sue.
My opinion is that Korra has some Mary Sue qualities, while still being realistic.
We see her struggle, and we see her be defeated a fair amount of times. But, when Korra was just four she knew most of the elements, even her opposite one fairly well. It's just airbending since she didn't have the peace she needed. Perfect, yet flawed. I honestly don't like her as a character, still don't, because for a while I saw myself in her. She had all this pressure, and was basically drowning while people were trying to help her. Yes, she has some questionable qualities, but don't we all? People miss that because "We're so used too unrelatable female characters that actually relatable ones are so annoying even though that completely explains me!"
With Aang, we see him struggle in Earth and Fire. Earth, his literal opposite element, not even his way of thinking and life. Fire, destructive, hurt his crush, and future wife, then his enemy uses it? We see his culture tested, and he runs away. I feel he is just as unresponsible as Korra, but a bit stubborn and a teensy pinch of mature. He was influenced, and many people miss that and just think he doesn't wanna do certain things because "OH, he's such a hippie even though he was taught things and lost it all!"
