I'm a little disappointed with it to be honest. The whole series looks like it will only go on for 1 or 2 season. The episodes will probably each have a moral story and not there won't be a reacurring evil villain in it. I'm also disappointed with the VA for Korra. She doesn't sound at all like an teenager, more like a 35 year old woman. I'm probably going to watch the first few episodes then quit unless it gets good. And don't say stuff like,"your stupid they showed the villain at the very end of the episode". I still have a few minutes left so just hold your horses.
edit: forget they did show a villain scratch all of that about the villain.
