My ten year old sister and I have been watching this series on netflix, and I must say, this is a truly wonderful show. The story is compelling, leaving us hooked from episode 1, and rather sad to see season 3 drawing to a close. I'm 19, and have seen bits and pieces of the show when it originally aired, but never got a chance to watch it all in sequence. I knew it was a fun show with a cool concept, but what surprised me (and has kept me so interested) was the level of depth. Zuko, for instance, is a compelling antihero (which is a rare concept in children's programming) who is struggling with morality, honor, and duty. He is aided (often in ways he doesn't realize) by his wise uncle Iroh. Iroh serves as both comic relief and a source of genuine wisdom (as opposed to the meaningless adages) throughout the show, and is again a character with depth and substance.

The Series's 3 main protagonists (Aang, Katara, and Sokka) develop magnificently as characters, to the point where you find yourself remarking on how much younger they seem in earlier episodes and flashbacks. And while you watch the show, you can feel yourself growing with them, sharing their journey as they do combat with firelords, seamonsters, and their own teenage lifestyles. Honestly, I have been enjoying this show to its fullest, and while it's not quite Crouching Tiger Hidden Dragon, it certainly isn't Kung Fu Panda.

Also it has a bunch of funny stuff/action that kids like.
