Avatar - The last airbender-

I like a lot of series, but this is the only one wich i have seen many times. Because I like the way that it has a lot of sense, in a spiritual way, and at the same time it's very funny and aimed at children. This series, with a fantastic/adventure gender, its about a fantastic world, divided in four different (in a human) kind of societies, distributed all over their world. Each one of this nations it' closely related to four different elements: water, fire, earth and air; mainly because of some people inside those nations who can control the element of their specific nation. There is only one person all over the world who can control the four elements at once: the Avatar, and his o her fate it's to keep the balance between the nations. Each nation is quite different from each other, thats why are the air nomads, the water tribes, the earth kingdom and the fire nation. Nonetheless, they lived peaceably for many years, until one day one of them, the nation of fire, thinking in their superiority, decided to expand their scopes, their power, and dominate the whole human world, so attacked the other nations. After one hundred years of war, and the disappearance of the avatar during all that time, this one, Aang, a 12 year old monk from the air nomads, appears on an iceberg in the southern water tribe, after be frozen 100 years because of escaped during a storm, due the pressure of the world tension. Just after that, all his people it's burned and killed by the fire nation and their only leader, the lord of fire of that time, who knew that the next avatar of that time had to born among the air nomads, so murdered all of them, except only one person, the last air beneder, the avatar (luckily). Then, Aang it's founded and coioncidentally awakened by two siblings from the southern water tribe, Sooka and Katara. There is also another character, Zuko, a prince exiled by his own father, the lord of fire, who sent him to look for the lost avatar and just then, recover his honor. This prince is lost beetwen good and evil: the support to his nation and the war, or the peace of the world.- This series has 3 seasons, and each one them has 20 episodes of 20 minutes each one, approximately, so, it's pretty good to watch some times when I´m boring.
