Bryan Konietzko, co-creator of Nickelodeon's hit Avatar: The Last Airbender, admits there's a great deal about the show he would change if he could. A Nickelodeon staple for several years, Avatar first premiered in 2005 and plunged viewers into a fantastical world where the four elements are represented by differing nations. In telling the story of Aang, the titular Avatar who has the ability to wield all the elements, the series offered complex characters, fascinating world-building, and plenty of heart. As a result, Avatar is widely regarded as one of the best kids' shows of all time.

Just to underscore how beloved Avatar has become over the years, it has led to the creation of its own franchise. Along with Michael Dante DiMartino, Konietzko created the sequel series The Legend of Korra in 2012 and wrote several comics set after both shows. Currently, the pair are working with Nickelodeon's new Avatar Studios to create even more content for the world of Avatar, starting with an animated movie. All of this is on top of the live-action series Netflix is still in the midst of developing, though Konietzko and DiMartino departed that project last year.

Both creators of Avatar recently appeared on the show's official podcast, Braving the Elements (via EW), and revealed new details about the making of the series. At one point, Konietzko got reflective when contemplating how some fans declare Avatar to be a perfect show. "That blows me away — there's so much that I would fix," he said. Konietzko then elaborated on this, explaining, "There's a bunch of stuff that I just think, 'Ugh, I wish that scene was animated better; I don't like the way this character's looking in this episode.'" However, he then admitted that "you can only fix so much."

Elsewhere on the podcast, both Konietzko and DiMartino admitted that Avatar season 1 episode "The Great Divide," an installment often criticized by fans, isn't all that good. It's clear that hindsight has resulted in a lot of new thoughts for the two creators, and it's understandable that there are things they might consider changing. Luckily, though, there are plenty of fans who believe Avatar is excellent just as it is, so Konietzko shouldn't take these things too hard.

Konietzko and DiMartino having a new perspective on their work on Avatar bodes well for the projects to come. Now that the two are more aware of what they wish they could do differently, they can apply those lessons to the future shows and movies. Much of those future plans for the Avatar universe remain unclear, but fans can rest assured both men have a lot planned. At the same time, there are others who might say Avatar is perfect as it is and doesn't need any more content. It's interesting how people can have different perspectives, isn't it?
