Okay, so here is the article I mentioned earlier:

Granted, I think the main reason there even is a comparison is because Hunger Games is extremely popular and they're using the popularity of that franchise to hype up Korra. But I still think this is an unfair comparison and it's pretty misleading.

I don't think Katniss and Korra have much in common other than the fact they are active female protagonists. I guess you could say they are both 'strong' and 'independent' as well but I think there are plenty of other female characters that are strong and independent. It's just these two happen to be the leads.

But other than that, the two are very different with very different personalities. Katniss is the archetype where she has to be more of a man than a woman in order to demonstrate independence. I'm not saying that's a bad thing but I think Korra is a tad bit superior in the fact that it doesn't take this route. It's almost like saying in order to be a strong female protagonist, you really have to be a dude in a woman's body. I don't get this impression from Korra and I think a lot of the reason why I don't get this impression is her voice. Her voice and her eyes actually. The way she's animated comes across as her being a girl but also kicking ass. And also screwing up.

Korra has had a much better life than Katniss, she's never had to fight to survive so she isn't a hardass like Katniss is.

If there should be any comparison between the Hunger Games and Korra, it should be Katniss and Mako. They're personalities are so similar: they're so focused on winning that they come off as cold. They've had to struggle to survive and have had to protect their younger sibling (this info is provided on the Nick website in regards to Mako) to the point where they've probably had to be the parent to the younger sibling. Which means that when the younger sibling is in danger, they will do whatever it takes to save them. Which is what I'm expecting when Bolin gets captured (featured in the trailers).

Actually, if Korra is to be compared to any character in the Hunger Games, I'm thinking she's most like Finnick where they're both upbeat despite the challenges they've had to face. Granted, they're not perfectly alike as Finnick's a complete flirt and has a lot more issues than Korra does but that's honestly the closest character I can think of in terms of parallels.
