An awesome show, for all ages really. I'm a thirteen year old who loves it, my brothers in college love it, and my dad loves it too. Many of my friends ages 12 - 16 also love this. Don't be hesitant because this show is on Nickelodeon - it's a great show and the best you'll find on that show. First of all, the production is great; there's awesome art, music, and voices. The world is great too. The Earth Kingdom seems to be based off China, the Fire Nation off Japan, the Water Tribes like Siberia and the Air Nomads like Tibetan monks. All of the characters are great, and their journeys are really deep and inspiring. There is a really cool story, and just enough filler episodes for you to get a great view on the characters and still not get bored, plus great humor. And in this engaging, deep storyline is a lineup of great lessons on revenge, war, abuse of power, good and evil, family, and biggest of all - that you can't judge people just from where they come from, that every person can do great things and in return, destroy things. In the beginning of the show you think that the Fire Nation is evil and the rest of the nations are good. But after seeing Iroh, Zuko, and Jeong Jeong you realize Firebenders aren't all badguys, and after seeing people like Long Feng, Hama and General Fong, you see that bad people can come from the other nations, too. However, the great moral of the story is that all of them deserve to be given a chance. As far as violence goes, it's really nothing to worry about - there is lots of action, but nothing bad is shown. There is war, but you don't see the killing that is implied. Several characters die, but their deaths are not shown. And there's little blood. Nothing to worry about in the sex department - there is lots of kissing but that is the extent of the romance, and throughout most of one of the Season 3 episodes, four of the main villains are shown in their swimsuits and bikinis, but it's really not too graphic. No bad language besides Katara calling her brother "sexist" once in the first episode, and definitely has no drugs, drinking, or smoking. Many of the deep parts also extremely emotional, the scene with Azula and her mother in the mirror is very, very sad but deep as you see her sanity deteriorating. All in all, it's great. Children will appreciate the story and characters, teenagers the sadness and action, and adults the strong life lessons imbedded throughout the plot. It's an awesome animated television show for all ages.
