Just a heads-up for those of you who may be interested in these shows: For a limited time, you can watch every episode of Avatar: The Last Airbender at the NickToons site. There are 3 books, that takes you to Book 1. Very much worth your time, even if you are *cough* somewhat grown up. :D It’s a great show to share with your kids.
Now, if you’ve seen Aang adventures, and are interested in Korra’s, there *IS* a way to watch every episode of Legend of Korra online too. First, from the A:TLA page above, you follow this link, which takes you to the Korra: Making of a Legend page. This gets you the first six episodes, interspersed with commentary from the creators. THEN you go to the Legend of Korra page at Nick.com, and click Full Episodes at the bottom of the page. That has the last seven episodes (it overlaps by one with the Making of a Legend stuff). Korra is also coming to DVD and Blu-Ray soon as well.
