"The Legend of Korra" is over. "Avatar: The Last Airbender" is over (long over- the last episode aired in 2008). Does the series, and the world it's created, deserve another spin-off?

Well, if you're an "Avatar" fan, that answer is a resounding "yes." Already, fans have poured out in support of the show and their desire to see more of it, starting a Change.org petition that's already garnered more than 12,000 signatures.

Say they fans, on the petition: "The Legend of Korra saw success as an online-exclusive show after it was pulled from Nickelodeon's regular TV broadcasting, and with Netflix's branding the franchise could be taken to new heights."

The petition suggests potentially starting a new series around the continued adventures of Avatar Aang, post-"The Last Airbender," or a prequel focusing on Roku, the Fire Nation Avatar who advised Aang during "The Last Airbender."

As well, a piece in Forbes argues that Netflix is the series' best hope of continuation, given that it's had success with picking up cancelled original series in the past, and that it's due for a new one soon (although an influx of Marvel TV is likely to keep Netflix afloat for a long while).

Netflix would be solid, but the better option might be an "Avatar" film. Another "Avatar" film, something the polar opposite of 2010's "The Last Airbender," the M. Night Shyamalan-directed disaster that gained almost unanimous hatred from fans.

A film could shake up the "Avatar" universe, could atone for "The Last Airbender," and could create something of greater intensity than a TV show that slowly builds over weeks of lesser-intensity stories. Most importantly, a film would require far less of a time commitment from series creators Michael Dante DiMartino and Bryan Konietzko.

In speaking to the Mary Sue, the two stressed that they're a little burnt out on the "Avatar' universe, and need something new.

Said DiMartino: "It's a little bittersweet. I mean, obviously we've been in this world for almost twelve, fourteen years."

Later adding, "So, yeah, it's been a very significant portion of my career now. Our careers. But I'm ready to move on, try some new things."

Bringing back these two is the most crucial part of any new "Avatar" goodness. And letting them take a break, then coming back for a year or two of moviemaking might be the best way to get it.
