"Hey, I'm going to forget all of season one and become an uber bitch towards everyone!" - Korra.
Seriously not happy with Korra in the premiere. She gets pissy over every little thing, and seems to have disregarded any sort of progress made with Tenzin in S1. Mako was literally just Korra's boyfriend. Sadly, that might be an improvement for his character. Bolin, pleasepleaseplease don't just be comic relief. He's my favorite character. I used to be a Korra/Bolin guy, but... yeah, Bolin's too good for her. Poor guy. Asami! Come back?
More vacation Tenzin (and family)! More Jinora!
Initial impressions: Unalaq == Tarrlok
Animation: KILL IT WITH FIRE. Very disappointed.
Overall, it was enjoyable but very fast paced and there were a lot of rather glaring issues. On the bright side, the biggest flaw (Korra's bitchy attitude) means there is a lot of potential for growth. Jinora's story is the most interesting to me right now.
