The only real 2 complaints I have about this show so far is:
1. The love triangle is rushed. Asami goes back and forth from being the nice girl that wants to be everyone's friend, to the jealous bitch worried about being replaced. Mako on the other hand loves Korra one minute, then wants to be friends the next. The plot line overall seems to be rushed to. In one episode we had: Somebody got their bending taken away, Korra breaks out and gets back with the crew, we meet Amon out of nowhere, Lin comes back and joins. It all just moves so fast.
2. The lack of moving around the city and staying in one area. Republic City is supposed to be huge but I feel like we're always in the same place. Air Temple Island or somewhere underground. Avatar The Last Airbender had too much moving around, and this has too less.
Sorry for the rant, I just wanted to get that out.
But nah, she's got the goods for Mako, even though Bolin basically threw himself at her. 
At least they're getting somewhere. That Aang and Katara kiss didn't even affect me since it took so damn long to get to it. 
I read somewhere that it's already finished and will have 14 episodes.
