I was actually really happy with this. The characters are perfect - I could practically hear their voices saying the lines as I read them. The art is slightly different to the animated series, which is to be expected, but otherwise I thought it worked well.

The plot is pretty much what you would expect to happen after the events of the TV series - Aang and Zuko's mission of bringing peace between groups that have been killing each other for a century was never going to be easy. The three chapters are essentially the equivalent of maybe a season of the show, but very condensed, and with a lot less filler scenes and side-plots.

And to the comment below about Zuko's mother not being mentioned: she comes up a lot in the third chapter, and it looks like that will be resolved in the next tie-in series - The Search coming out in March 2013.

The only issue I had with this was the romance between Aang and Katara. The majority of the scenes where they interact are lovely - subtle, and yet clearly demonstrating their affection for each other. So then when they randomly start to call each other 'Sweetie' and the artist draws hearts all around the s as they stare into each other's eyes, it seems both out of character, and unnecessary.

Otherwise, very worth buying.

I most definitely would have liked "The Promise" to become full fledged ongoing series. Something to complement an actual feeling of a 4th season to the original series.

Although I've only read the first 2 chapters of this series, each of those chapters seem to be too short.
The art-style seems to appear different from the original art. My only disapproval is the way Zuko is drawn. And I hate the fact that Zuko's mom has never been mentioned through out these chapters. I know that such things will be mentioned in the "Legend of Korra" television series... but it would have been great if they mentioned it in the first chapter. I also would have liked to see Azula's ambitions after her defeat.

I'll give it a 10/10 because I really found it amusing how Aang gave into anger and went spirit-mode activation.

The way they started the series, the color-art, the new outfit designs of each character, and even romantic aspect - was very well done. So to make things clear, although each chapter seems to be short, the story still offers a balanced nature that gives the story a well respected fashion.
