I have a very hard time liking Korra. I find her to be stubborn, selfish, irrational, overly aggressive, pigheaded, immature, and obstinate. This list of adjectives can keep going, but I digress.
When LOK started, I was somewhat excited for a female avatar; my feminist side was all for a powerful female lead that would lead the avatar world to a time of peace. However, to my dismay, Korra was a strong and powerful character, but her other characteristics and personality flaws overthrew her potential as a character.
In Book 1, Korra basically does whatever the hell she wants because "she is the avatar," and this reasoning is what she repeatedly uses as her excuse to do as she pleases. For example, Korra destroys property and expects that the law can be bent for her because of her status. She uses this status and power to abuse the system. It's actually quite ridiculous. And naturally, this logic that Korra spews becomes the norm as Korra never has to suffer any consequences for her actions. Everyone who backs her (Tenzin, Lin, the Krew, etc.) blindly follows her and accepts whatever she does as if there were no other choices in the matter. Even if Tenzin and Lin think otherwise, their ideas are cast aside because Korra won't have any of it.
For example, Korra joins the pro bending team, despite Tenzin's wishes that she go back and train at the camp, or that she remain with him on Air Temple Island to master air bending (and air bending be her only focus). Korra cannot be bothered to learn the element, or at least she can't find the capacity for her to "focus" on the task. Korra is the opposite of Aang, which is great because this gives us diversity. The problem is that the writers made her so different from Aang, that Korra acts as if her position of avatar is a nuisance. Korra can't be bothered to adhere to her responsibilities because more exciting things that she wants to pursue come first. This brings me to my point of Korra irrationally putting her own desires first, rather than her responsibilities as the avatar. This is displayed on numerous occasions in the first book, especially with the love triangle nonsense. Mako is happily dating Asami, yet Korra can't be happy for her friend's new relationship. Rather, Korra immaturely mocks Asami, calls her prissy, etc. The sad part is that Korra's jealousy is so evident, and she doesn't seem to realize how childish she is acting.
Korra intentionally leads Bo on (knowing that she doesn't want to pursue that relationship) and then kisses Mako while she knows he is in a relationship with Asami. Korra selfishly put her love drama first, and she did not care who she hurt in the process (Bo and Asami), because as long as Korra was happy, then nothing else mattered.
While all of this bullshit is going on, a HUGE problem is happening in Republic City. Nonbenders are being oppressed and they are trying to start a movement that actually focuses on why non benders are not happy with their current conditions. The non benders want to be treated equal.....now isn't that a first? And naturally, when Korra finally decides that "oh right, I'm the avatar...I should do something," Korra doesn't even try to understand what these people are going through. She doesn't try to hear out what their movement is or what their causes are. Korra obstinately refuses to listen and states that the non benders are oppressing themselves. Great avatar.....-_-
This saga continues until we finally hit the end of a rushed book that has so much going on that a good majority of us forgot the main point of it all. Korra brashly decides to go after Amon, and in the end when Amon EXPOSES HIMSELF (and later dies by the hands of his brother), Korra then takes credit for it, as if she was the one who exposed him and then defeated him. Yes Korra, you did everything by yourself. -__- And then of course, she lost her bending (except air), and then magically Aang appears and restores her bending when she sheds a tear......all conveniently put on a platter for an avatar that didn't work for it at all.
And then we get to Book 2 where the equalist movement is magically resolved, and a new problem arises with Spirits. Korra is preoccupied with her new bf, Mako, and during all of their scenes, they treat each other horribly: fighting, Korra blaming Mako for not supporting her because he didn't agree with how she is handling all of this spirit shit, Mako is irritated that Korra doesn't follow the lawful code of conduct he does (lol at Mako now being "moral" and "ethical" and "lawful" Kettle meet Black) etc. This at least for me was some poetic justice for the fact that things aren't always greener on the other side.
And Korra brashly follows her random uncle's plans (yes, that uncle that she has just met and is shady AF), despite her dad and Tenzin being against all of it. And then Korra states that she's all mighty and powerful after defeating Amon and she now knows how to air bend/is a master (yes air punching is mastering). And then Korra gets attacked, loses her memory, yada yada......this all was done to improve her character, yet that shit didn't help. And then she comes back and then fights her uncle as she makes some of the dumbest decisions of her life. And then after Unalaq is defeated, Korra says she did it all by herself (yet Jinora did more shit than Korra), and of course leaves the spirit portals open without really thinking through the repercussions (but this is a typical thing for her).
And now we have Book 3, where Korra is now worried about her approval rating and complaining about the effects of her decision (like this is why we should think things through). And then she gets angry at the President who is against her decision(s).....and she never even tried to hear this guy out. She was still pissed at their tiff from the past season (because he didn't jump on board with her plan, and wanted a peaceful, nonviolent, and diplomatic solution). Good grief.... -__- And of course, air benders appear which means that now Korra's half-ass decision is now justified because the convergence created a breed of new benders. A NEW ERA.....whoop-di-doo.
Korra still keeps her hostile and over the top aggressive behavior when trying to recruit benders -__- and then throughout this season we've had Korra making every little thing about her, her playing the woe is me tale with "everything is my fault" etc. The world revolves around Korra. I've seen some minor growth from her, and it is pitiful. We even have Korra mastering metal bending in a day which is beyond Mary-Suish.... I can't even wrap my head around Book 3 trying to make up for the first two books of poor writing.
Point being, we have the same reoccurring theme throughout these books. We've got a self-centered, stubborn avatar that immaturely and irrationally makes decisions based on her emotions and desires, rather than looking out for the good of the entire world. And even when some decisions she makes are good, they were made off of a whim, rather than her fully thinking things out thoroughly or even considering the repercussions of her actions.
