I don't know from where to start as everything in this series is perfect. I HAVE WATCHED(full season) IT OVER A 30 times and even now I FEEL IT TO BE WONDERFUL. The plot is an epic. Creators took ideas from from ancient Chinese and Indian culture and mixed it with creativity to create this EPIC. The 5 elements idea is the main aspect(even though 4 elements- air,fire,water,earth was considered in series leaving Sky).The plot is very simple but also very exhaustive and creative. Even a child can understand the plot but also a person can write a thesis on it.

Secondly the action, this series has a action which is on it's own a different kind. In this series action is mixed with philosophy. But it is above par when compared to other series. The excitement through the seasons remains high and constant. It also includes some tactics(a lot) and politics.

Character development- EACH AND EVERY CHARACTER HAS GREAT IMPORTANCE even though some characters are made for sarcasm (like cabbage man, sokka),the sarcasm is very effectively produced. Another thing is many of the characters are PERFECTLY DEVELOPED and are VERY CREATIVE CHARACTERS. THE WORLD IN THIS SERIES IS VERY BEAUTIFULLY SHOWN WITH WONDERFUL ABILITIES TO CHARACTERS.

MUSIC/OPENING-music is too good, it is very pleasant to hear, It is like the gentle shower falling on leaves. OPENING IS PERFECT IN ONE WORLD.

Romance- The katara aang(kataang) romance is epic, It is very hard to describe,BUT don't worry just watch the SHOW.

ENDING-BOOM BOOM FULL OF ACTION and one of the best endings ever seen.

FINALLY, IT'S HIGHLY RECOMMENDED IRRESPECTIVE OF AGE, WATCH IT THINK OVER IT, FINALLY TOO GOOD FOR THIS EARTH.
