This is the third meme I've submitted in a row that defends Korra (both the character and the show), and I figured an explanation is in order.
It always frustrates -- nay, disheartens -- me whenever I see hate towards Korra not just on here, but just about anywhere on the Internet. I've seen people fault her for her personality in Book 1 (which her personality improves as the show progresses), calling her a failure because she didn't defeat Kuvira during her duel in Zaofu (which is ableist, because Korra had PTSD after nearly being killed by Zaheer and the Red Lotus), putting too much emphasis on her faults rather than her strengths (that in which one her strengths is becoming the first Avatar to master metalbending), and hating her simply for being a bisexual woman of color who is in a relationship with another female (which is both sexist and biphobic), among other things. I've even heard worse things about her, but I don't wish to bring it up.
The point I'm trying to make is that Avatar Korra is no Avatar Aang, but on the flip side, Avatar Aang is no Avatar Korra. Korra never tried to be like Avatar Aang, which doesn't make her better or worse. Just different. And she should be accepted for who she is.
