I feel that there's a lack of "goal" for this season series. Last Airbender focused on defeating the Fire Lord and stopping the war.
This season was... Korra goes to learn Airbending - okay, that stewed in the background a little... then pro-Bending - well, that was two episodes and done... then Amon - oh, wait, now he's dead. Oh, Korra lost all her bending? That's something to build... oh, wait, no, she's got it back again. Now what? Oh something, something spirits, civil war, politics, something something...
Still, better than most animated shows on TV right now.
They released a Korra season 1 soundtrack. It's flipping amazing. Wish they'd release something for Avatar.
