1. Let's get this out of the way. Jinora's "I must go. My people need me." Was the biggest cop out/deus ex machina thing ever.
3. While Wan's idea was outdated, I don't agree with Korra. Humans are less spiritually aware, and they have began to move towards a more industrialized world. Sure the smaller villages + spirits would make sense, but imagine spirits trying to run around in Republic City? That would be a disaster. One Avatar can't solve problems if spirits and humans are going at it in various parts of the world.
5. Bolin/Eska was totally stupid. Wasn't this guy trying to go after Ginger? And then out of no where he has feelings for Eska? Especially after what she did to him? I swear, those two brothers make zero sense.
6. Bolin's jail visit to Mako was over the top douchebaggery. He also had zero repercussions for being a total douchebag ever since he became a movie star.
7. Unalaq's motivations were still not properly explained. So you want the spirits and humans to live together and be their ruler....um...why is this a good idea? Especially if it's going to be dark spirits.
10. I was hoping Lin was playing naive to Varrick and knew what was going on. NOPE. Total ******* chief they got in RC. What's even more hilarious is this: She refuses to listen to Mako for his "speculation" and "shady evidence." But when she gets a random tip that Mako maybe hiding some explosives, she decides to act on it? WOW.
11. Asami was once again literally there to be "Mako's boyfriend". She's practically useless if she's not doing that.
I agree with all of your points, only quoted those I want to elaborate on.
1. Seriously, what was that? “Looks like all hope is lost, so have this random light ball to shift the balance in your favor”? And that after Korra had already connected to the principle of light, and thus shouldn’t depend on its manifestation Raava any longer? Also, if the thought behind this is that Jinora found the reincarnation of Raava (as “one cannot destroy the other”), why would she place it into Unalaq and not directly into Korra? We didn’t see any remains of Raava being absorbed by Unalaq, he merely destroyed her.
This
was followed by Unalaq mutating to this huge being, but if that is to be interpreted as him absorbing Raava’s energy, he should have lost his size after Korra took Raava away from him again. Also, Korra managed to attaing hugeness simply by connecting with her inner/cosmic light, so why wasn’t the much more spiritually experienced Unalaq able to become huge by connecting to the cosmic principle of darkness? Maybe it was because he didn’t have access to the magic tree, which was occupied by Vaatu.
(3) But if that’s the reason, with the portals and the tree available to every human being at the end of the season, pretty much anyone could have gone there and connect with cosmic energy and become a huge glowing thing – when Korra did it, she was nothing special as she lost all of her Avatar buffs and wasn’t particularly spiritual anyway. Doesn’t seem all that balanced to me.
Nor does everyone being able to thwart death by imitating Iroh and just go back to the material world through the open portal.
To be honest, I found everyhing the “light vs. darkness” battle came down to was extremely bland and shallow. The way of interpreting this ongoing battle that felt the most logical to me was light standing for selfless giving and darkness standing for selfish taking without giving. But then we had light super-Korra eliminate Unalaq and Vaatu. Not a very selfless, loving action if you ask me. To Vaatu, it might have been redemption as he was a very tragic being – condemned to flourish and grow only by corrupting and taking from others by force. But to Unalaq, who had been a normal living being, it would have been way nicer to just, like, free him from his obsession with darkness. Which is also way more likely to be the result of Korra’s exorcising ceremony. The argument that Korra made later – she couldn’t redeem him because he was already fused with Vaatu – doesn’t really count as Unalaq managed to extract Raava out of Korra just one episode early. Now you might say that Unalaq was only able to do that because he was merged with Vaatu, but as huge Korra seemed more or less on par with huge Unalaq – losing in the end because Korra as a human was weaker than Unalaq, just like when both were avatars –, we can assume that Korra’s light imbue is more or less equivalent to fusing with a light or darkness spirit.
To come back to the “good vs. evil”/“light vs. darkness” concept, this last episode made me appreciate the end of the Nausicaä manga much more. [collapse=You probably need to have read the manga to make sense of this]While I previously didn’t really understand why the distinction between the tomb fighting for the preservation of the life of the human species, and saying “Life is light!” and Nausicaä saying that “Life is the light that shines in the darkness! All things are born from darkness and return from darkness”, I now believe that to be a much more profound vision of hope than the similar biblical quote that excluded the latter part and with it, darkness from god and life. By also embracing darkness, Nausicaä abandoned her deepest fear – the fear of nothingness – and trusting in life ever coming forth out of darkness, even after all life on this planet is gone. [/collapse]
5. Every romancey stuff in Korra made me cringe. There were so many scenes that had both characters moving away from each other, only to start kissing out of the blue when it really wasn’t appropriate.
Mako acted like an asshole to Asami several, who should have gotten really mad at him, but as you stated in
(11), that was more than her one-dimensional character role allowed. And Bolin is just plain dumb and unfunny.
(6) Mako
not being mad at his brother after he treated him like that at the prison and
nobody calling Bolin out on his bs had me almost wonder if Shyamalan was responsible for parts of the character design.
7. At the beginning of the Unalaq revelation, I hoped for a moment that Unalaq had valid critique on the avatar concept that had been going on for ten thousand years. But nope, he didn’t want to achieve balance at all, he only wanted to shift the light/darkness balance from +1 to −1. Because being huge and glowing purple is so much fun, I guess.
10. Lin’s character was completely lost during the second season. Admittedly, she hadn’t been that much better in the first, but her not even considering Mako’s theory made me lose all respect for her, and in the last episode, she should have resigned for such a bad decision.
I don’t regret watching this season to the end and I will keep watching Korra as it’s still an enjoyable series with great animation, but the hope that the quality of the story, humor and dialogues will finally reach / exceed the level of the Aang series is finally gone for me.
). And I thought the pro-bending plot could have been better executed and the resolution with Amon was way too hasty. But obviously that was because of the episode limit. Still they tried to cram too much in.
