It’s good that you likes it, it does has its moment, but it destroyed the whole foundation set by the Last Airbender. Korra had issue, but the issue of the series doesn’t really stem from her character, it’s the whole setup. Like i said, the plot push forward purely by “it just happened”, smart guy Zaheer didn’t even know power vacuum will just lead to someone replacing the throne, third season story is purely “Zaheer just happened to have airbending power”, season two Korra just happened to know how to goes Blue Ultraman to fight Red Ultraman, so on and on.

And yes, Korra may be on her ass all the time, but all her suffering is her own doing. She being an ass to Tenzin in season 2 lead to her getting her ass kicked and all the connection to previous avatar severed. She allow the portal to remain open lead to Republic City’s overun with spirit vine, and her getting her ass kicked and mercury poisoned, which lead to her further suffering along with Republic City getting destroyed in season 4. It’s a serious issue with the writing because unlike Aang, where his suffering isn’t his own making, the writter make Korra constantly making the wrong choice which in turn lead to her and everyone suffering.
