...t introducing/developing the main characters in the first season and making them actually likable. How long did we spend introducing Katara and Sokka, their backstories and motivations before we even met Aang? All the way to the end of the series the main group of characters was still a small, core group. Legend of Korra tried to go way too big way too fast. For this reason the show didn't really gain traction until the second season, and kept losing it as it bounced around all over the place.
