'The Legend of Korra' Book 4 Trailer Is Finally Here (VIDEO)

The Legend of Korra has had one of the most tumultuous scheduling legacies of any show in Nickelodeon history: after getting moved all over Friday nights, the show is moving completely online for Book Four.

So what can we expect from the final season of The Legend of Korra? Well, the season is titled "Balance", but we don't really know much for certain beyond that. Book Four premieres on October 3 on Nickelodeon.com, with new episodes following every Friday after.

With new episodes debuting next Friday, now would probably be the time to get excited, even if it is kind of bittersweet. There's probably an argument to be made that this shouldn't be the last season, but at least creators Bryan Konietzko and Mike DiMartino seem to have a conclusion planned that's worthy of the previous three seasons that came before it. But what do you think of The Legend of Korra Book Four? You can check out the full trailer below:
