It's an OK show on Nicklelodeon. OK, not great. Infact, it's just above the shitting line. It is you're classic, I'd say stereotypical, good-vs-evil, children-saving-the-world plot. Most people just like it because of the animation... and, no, it's not anime. It's American animation imitating Japanese anime. At least it's not as bad as Teen Titans. The characters are cliche'd such as Aang who is like Goku from DragonballZ. Soka is like the smart-ass, sexist comic relief and Katara is like the wise, feminime runner-up character who will probaly end up falling in love with Aang like most kid-directed shows. Unless, Nickledeon thinks that is inappropiate. There are, of course, the ultimately bad guys but, no neutral side army. It has some good moments and then, the not so good. Overall, I'd rate it: 5-10
In my opinion, Avatar: The Last Airbender is kind of boring and predictable.
