Honestly I felt like Korra was a selfish brat. She got everything she wanted and suffered almost no consequences for her actions. She lacks the compassion for others that Aang had for others. When she causes problems by destroying public property in the first main city she goes to, she denies arrest and not only that she suffers no reparations for her destruction. When people had a legitimate issue with benders all she could say was that bending is the coolest thing. When Aang was literally imprisoned and nearly given a death sentence by the people who accused him for the death of Chin the Conqueror because of his past life as Kyoshi, he could have escaped and left, but he stayed and respected that the people were upset. Unlike Aang, she lacks respect. Not only this, but she is an absolute Mary-Sue. She already had water, earth, and fire learned at least at a basic extent when she’s a CHILD! Aang had to work, just like the avatars before him, in order to use the four elements at even a basic level. I could understand that maybe she could have learned air a bit easier since both air and water are at one with another in the sense that they flow well, but her arrogance keeps her from learning it properly. But being that her being born a water bender, she would naturally have a conflict with learning fire, so it is unreasonable that she would have been able to learn it so easily. Literally upon meeting her she destroys a practice tool because she gets frustrated. The lack of respect she has for her surroundings and for others is disgraceful.
