I want to like you, Korra. I really do. Her emotions are all over the place. I look forward to that calming down. The bit with her reuniting with her parents was way too rushed, but it was at least a nice touch. Unalaq, you jerk.
Seeing Mako outside of his relationship with Korra was nice... even if he was just playing a very similar role with Bolin. Also, Bolin's shot at Mako was hilarious. "I'm lucky you're so good at breaking girls' hearts. Korra'd better watch out! Oooh..."
Vacation Tenzin took a rather serious turn. That's okay though, because I liked it. It is a bit strange to see these rather old siblings acting like they're under 10, but despite that, I do like both Kya and Bumi, and I look forward to seeing how the three resolve their differences. Also, learning more about how Aang may have been great at some things, but maybe not so much at others is a very nice touch.
Asami! Come back!
The animation still feels off. The scene where Bolin, Mako, Korra, and the twins are at dinner really stood out to me. After the twins leave, Bolin starts freaking out, and Mako and Korra both remain completely motionless the whole time. No reaction or anything. Also, some of the action scenes looked a bit odd. Some of it was very good, though.
Overall, decent. I don't want to judge this episode too heavily until we've seen the complete arc.
