Garoo

I wasn’t thrilled with this season of Korra, but that was a great finale. (I’ve tweeted the same thing every year, haven’t I?)
A discussion on Twitter clarified why: I enjoyed spending time with The Last Airbender’s major characters, even when there was no action, whereas the entirety of Korra’s cast is annoying, so the show is only fun when big story moments happen. Jinora is pretty much the only exception, but she is more of a plot device than a developed character.
