Good original series. Love the art style. After rewatching the whole season, i found that legend of korra was way better in terms of plots, storyline, world building, characters' developments, villains and mystical creatures. In short overrated. Most of the casts were becoming more annoying as the series progressed. There are few great fight scene but not a fan of the villains as they seems weaker compared to the ones in korra. The whole series stay in one plot which extensively used for the whole series of 3 seasons, in short boring.
