The new Avatar series is definitely good, but is it as good as it's predecessor?
Obviously not, a sequel is a sequel.
I loved this episode, and the animation was beautiful. Korra running through the city was pretty funny, and the face Lin and Korra made at each other was priceless, which was one example of the recurring humor that appears throughout the show. The new city is amazing, and designed fantastically.
One thing I noticed that was out of line from the previous series was that Korra knew she was Avatar fairly early. She could bend all three elements (though poorly) when she was very young. Aang is obviously a superior avatar in learning all four elements in one year, Korra had 17 years to learn all three. Ah, don't get the wrong idea... I love Korra.
This is just an introduction episode, basically, showcasing Korra's arrival to the city. It's definitely a worthy episode though.
