If you think this is just a kids show you will be surprised. Yes, children are sure to love it, but I watched this as an adult and was amazed at the story. The first episode requires a little bit of patience, it's not boring but it's easier to dismiss especially if you are not used to animated TV. But after that I was hooked. The imagination behind this is incredible. There is suspense, a spiritual background, humour, romance, martial arts and compelling visuals. I don't usually rewatch a TV series but might give this another look. If you haven't watched it yet, lucky you that it's on Netflix. Enjoy! And after that, there's Korra, a sequel series also very good.
