I've been lucky enough to have seen this show from inception to end and again many times after. In modern day animation and story telling it's nigh on perfect. There's plenty of other reviews here that go deeper into detail but for me it's a show with heart,humility,humour and it's message can,should and hopefully will transcend generations. Already my two sons love it and have watched it several times.

The scenes where Aang enters the Avatar state still give me goosebumps.
