I Love Rifftrax
Yes, I doubt the creators had racist intentions.
I'm just pointing out the unfortunate implications when you show someone as dark skinned as a child and then light skinned as an adult, if people want to complain than they are fully within their right, but I'm prob not gonna say anything else about this because there is nothing really more to say. They shouldn't have done it, lets leave it at that.
It was likely a colouring error (I hope) and not intentional.
About what someone was saying earlier, I do agree that the show has some pacing issues (prob because they squeezed it all in to only 12 episodes). And it did feel like Korra got it all handed to her in the end.
Also, remember at the very end when she rejects Mako's love because she has lost her bending and doesn't feel very worthy of his love?
Thats a pretty big issue to explore. It seems Korra's entire self-esteem is based on her bending ability, without it she feels unworthy as a person and unworthy of love.
I would have loved it if they didn't give her her bending back so quickly and instead gave Korra a chance to grow and learn her self-worth as a person. Give her a few episodes of season 2 learning to cope without it and learning to love herself regardless, it would have been great character development. But NO, they had to give her her bending back and instantly make everything better and she runs off into Mako's arms.
