Avatar is, to my mind, the greatest animated series ever made. And I do not say that lightly. I love animation and have seen literally hundreds of series.

There are a number of reasons I say this...

1. The lightness of tone, which actually is a cover for a deep, powerful story of personal discovery and the futility and loss of a planetary war, among other things.

2. The excellent voice work by all concerned.

3. The profound messages gradually parcelled out over the episodes.

4. The excellent handling of the different elemental powers: no type of elemental power is better than any other, it's the skill of the individual that counts.

5. The friendships between the characters...this is just lovely.

6. The development of the story through each episode. There is no real filler here as far as I see it, just a carefully planned story that makes perfect sense, and characters that always stay in character moment to moment.

I am sure there is more to say, but I don't want to give any story away, so I will leave it there.

Similar to Adventure Time, my second favourite animation series ever, the action seems quite childish at times, but if you look below the surface at the themes being addressed, you will find something more adult than 90% of 'adult' series.

Wonderful, just wonderful.
