I have to agree, I was skeptical at first and there were a few difficulties I had accepting the animation style and the movement within it, but once I passed the first episodio I got hooked by it and watched the whole thing almost none stop.
Amazing series, incredibly familiar to Avatar the last air bender, and yet, it's own right thing, it really has the potential to continue to deliver and Im already looking forward to watching the next season with the same amount of funny and touching moments.
