Avatar: The Last Airbender Season 2 (2006)

"It is important to draw wisdom from many different places. If you take it from only one place, it becomes rigid and stale. Understanding others, the other elements and the other nations will help you become whole."

Having sufficiently learned waterbending, Aang and the others make their way to the Earth Kingdom in search of an earthbending teacher and to bring crucial intelligence for the war effort to the Earth King in the capitol of Ba Sing Se. Along the way they are harassed by new antagonist, Azula. She is a Fire Nation princess, bending prodigy and a far more dangerous adversary. As Zuko's sister she is sent specifically to succeed where Zuko has failed. A recurring subplot is Aang attempting to master the Avatar State; a superpowered state that affords him the power of all the past avatars. This proves more difficult than bending since there are benders abound, but there are seemingly none who can teach him how to be an avatar.

This season continues the precedent of excellent animation and surprising depth for a kid's show set by the first season while bringing in a fresh batch of the new. New characters, stories, and new twists on old characters particularly on the part of Zuko as circumstance forces him to deal with a new set of problems other than hunting Aang that may change him forever. Any problems of the first season have been remedied and the show hits its stride if it hadn't already. Best of the old and a slice of the new equals some fine entertainment.
