As a child I loved this show for its action and colorful graphics. Not the most refined way of viewing but its what got me hooked. About two years ago I noticed a lot of others re-watching Avatar and went back to watch it myself. This time though it wasn't the action or colors that held my interest It was the characters, the story, and its surprisingly advanced themes. Almost none of the characters are flat or one sided. From the main antagonist having a moral crisis to a street vendor completing an off screen story arc Avatar does not fail in the development department. The story isn't just a string of small vignettes like many other "narrative" focused shows. It has defined beginning, middle, and ending story lines. In season one the audience sees the basic story setup for the whole series and its own climax and partial resolution. The second season gave depth to the shows main characters and had its own climax and partial resolution. While the final season ties up many loose ends and of course completes the series. All this is happening while amazing adult life lesson and themes are sprinkled around in every episode. Over the course of the show we're given dozens of eastern anecdotes and shown themes like redemption, ambiguity, indifference, conditioning, and sacrifice. With these three major pluses going for the show I have to recommend this to everyone. It will not fail to catch, hold, and turn your interest over its three seasons.
