But other than that. Here are the good parts:

First appearance of Varrick and Zhu Li
Uncle Iroh and Zhao cameo
More insight of the Spirit World.
The story of Avatar Wan
Civil War between the 2 watertribes
Bumi became a badass and saved the Korra gang like a boss
MOVERS!!!
Unavaatu (and giant spirit Korra duking it out)
The soundeffect of Unavaatu's laser
Overview of the round Avatar earth (and other planets)

I can probably think of a few more things, but for me, it was a good season (then again, I'm mostly easy to please)
