Great series. It's one of those cartoons that seeing one episode just makes you want to watch more (at least for me). There were many episodes where Sokka had me cracking up. Great storyline + great character development = enjoyable cartoon.
I have caught up in all the Series. During the break or filler episodes [the filler episodes bring down the overall quality of the series. The animation in those episodes are atrocious and the storyline contributes little to the overall story] I started to read the Manga. It is all pretty good to me. I like the Themes and concepts. A well thought out 'world' Avatar is as well. Some of the campy humor is hit or miss. Some of the solutions are a little to 'pat' [in both] Quality tv though. My son got me into them. Rocket River
