Comment on first part: The mist in the Spirit World was pretty interesting, especially seeing Zhao there still raving about Aang after all that time. But the second half of it was a little bogus, Unalaq with Vatu suddenly decides that he has a new power that lets him manifest a tendril out of his mouth, face-hugs Korra, then sucks Ravva out. Shouldn't Ravva have told Korra she could do the same thing? Or is Darkness always just going to be whipping around the Light side all of the time because Darkness is never ending and always all powerful? Then Ravva gets pulverized into a stone and the past generations of Avatars get deleted apparently. And before Vatu fused with Unalaq, he was still more capable than Korra in a fight. Afterwards, even more capable and she basically didn't stand a chance, even though he just started using three other elements all right then, though I can only say that I saw Earth and Water possibly, or just a lot of Ice being used that can fill a role of Earth, would have to watch again to look at it closely. Comment on Second Part: Tenzin: "I realize I haven't been the best mentor to you..." Lol you've been fine dude, it's not your fault Korra was an unwilling and emotional brat for most of it, Tenzin doesn't know or can't do everything, that's nothing to fault him for. "Korra's back! And she's a big blue giant!" Babe the Big Blue Ox reference? I don't get why when she has him pinned to a rock near Republic City, that she doesn't slug him a few times first to make sure he'll stay down for a few so she can check for the Light in the Dark. Classic mistake to hit the bad guy once or twice then think "Nah he'll stay down so early so I can do what I need to". Otherwise it's a good ending to the second Book/Season, I can guess that the next season will involve drama with the Spirits coexisting with Humans, and Korra regaining her link to the past Avatars most likely, since there's no way she can be the last one, but where it will go still I don't know.
