As far as I'm concerned, this is the best series, I do not know if it's ever because I've lived only 19 years - but it's just great, fun and nostalgic. The series is of course a fantasy, in a world where there are people who can get out of their hands or spell or attack - of fire / water / air / earth The series tells the story of Aang, an air- spell whose nation was completely destroyed by the brutal fire nation. Aang, who froze himself in the glacier, awakens 100 years later with his flying bison Appa into a terrible world in which the fire nation approaches global domination, terrorist and dictatorial domination. Ang awakens when he is found by younger brothers from the water nation - Sokka and Katara, and together with them he sets out on a journey that has lasted 62 wonderful episodes, and 4 seasons. During the journey, Ang and Katara fall in love and the plot tells it perfectly. The plot of the series is fascinating, the best season in my opinion is the first. During the wonderful journey, so many wonderful and fascinating stories unfold in the children's journey, I prefer not to expose them to those who have not seen her - and to you who have not seen her - I just feel sorry for you, because you miss one of the best series the world has ever known. I'm not inclined to give a rating of 10 - and the series is one of the few pages on IMDb that will get me 10. It's hard to explain what's so good about it, you just have to see to understand. Finally, for me this is the best series I have ever seen, and the legend of Cora undoubtedly continues the excellence of an avatar - but for me it will always be less nostalgic than Avatar, and a little less good.
