The Legend of Korra - Book 2: Spirits

Oh wow. I've just watched episode 10-14 in a row. That was good.

 Spoiler

Though I did not like the ending. I was assuming Ravah would win, and the next two seasons would be focussing the story afterwards. Instead Korra saves the day in a matter of minutes. It suprised me, but I think I would've prefered the other option.
And like others stated; the heck was going on with Jinora?

Noting the post above made me think. The combination of all air nomads being wiped out during the Aang era and Korra losing the connection to her past lives. Imagine how weak the general ability to airbend would be now. Much knowledge is probably lost.

Did you mean you expected Vaatu to win?

You bring up a very good point with Air Nomads. I wouldn't be surprised if some point in the remaining two seasons they will go over that. If you noticed, however, more than just Tenzin's family was in the Air Temples, it's likely that Aang passed on the Air Nomad traditions to non-Airbenders in anticipation of the Air Nomads being restored in the future. They might not be able to Airbend, but they may know a lot about it and were instructed to pass it on to future generations so that the Air Nomads could be revived.

Side Note: I really wish they had just done a bending battle royale after giving Unalaq all four elements for some crazy reason. It would have been a whole lot better than the giant spirit form battle like we got, visually that is. That battle was pretty bland and uninteresting, but Korra vs Unalaq before Ravah was ripped out was extremely entertaining, reminiscent of the battle between Ozai and Aang. Probably would have made more sense, too, considering Vaatu's defeat made almost none to begin with.

I feel like they intentionally broke the link between Korra and the old Avatars so that they had a plotline of her attempting to recover it, even though they didn't really need to make one considering the ending. Overall the Avatar State was pretty disappointing this season. Korra should have been far more powerful than she was considering what we saw from Aang and his predecessors.
