It takes a while for the show to find its footing, but when it does its usually firing on all cylinders. You can definitely see a progression of the character arcs and plot, and the subject matter does indeed grow with the characters I would say. OK, let me rephrase: does the cartoon develop beyond kiddie potty humor? When the show first started, Aang's character would creep me out. I get that he's supposed to represent (especially in the early going) freedom, fun, humor, and innocence. Basically, as he's introduced, I believe he's meant to personify the bedrock symbolic qualities associated with an idealized child's perspective. Then the whole Spoiler (Move your mouse to the spoiler area to reveal the content) Show Spoiler Hide Spoiler genocide thing kicks in and the flat representation becomes a true character. He creeped me out because I believe they overdid his childishness in the beginning by making him burst out laughing for no reason. Well, he'd do something daring, or naughty--jumping off the side of a cliff--and on the way down, before bending his way out of trouble, he'd cackle the whole time. He was like the Joker, except he wasn't a psychopath, and his voice sounded, to me, like Charlie Brown from those decades-old animated Holiday Specials. Good grief, Aang, you're hopeless! Go save the world already! Take 2: It's the Firelord, Avatar Aang! One aspect of his very early personality his developers phased out as the show went on was that he would stick his tongue out whenever he did something cool: Jumping off the side of a cliff, and then not dying. One of my earliest heroes was Michael Jordan, who'd characteristically stick his tongue out whenever he did something cool: Absolutely denying any other non-affiliated professional basketball player the sweet taste of a championship, unless he chose not to play. Also, he summarily denied the sharing of even 1% of NBA poster sales between the years of 1992-1998. Whether he stuck his tongue out doing this can only be hypothesized, never proven. Aang sharing this trait led me to believe either DiMartino, or Konietzko, or both were/are Bulls/Jordan fans. Anyway, Aang eventually stopped doing this, and it made me sad (It's always nice--but never necessary--to get to the point). The show, taken in as three seasons-worth of Action/Adventure/Comedy, is excellent, and well worth the investment of your time, money, and attention, Koohii. This is coming from someone who is very hard to please, so hopefully it adds an extra layer atop my already bubbling enthusiasm.
