Avatar: The Last Air Bender was great because it was incredibly thoughtful for a childrens show and gave the avatar Aang a lot of big issues to work through. There were love stories, but they evolved over time and didn’t take up all of the screen time. With Legend of Korra, it feels like the writers decided that now that there’s a girl at the center of the story, the show has to turn a high school gossip session over who-kissed-whom. Instead of spending time on character development, Legend of Korra mires its characters in absurd, round-and-round fights over who gets to date one another.
