The best thing that I found on this animation is a movement in action scene and an interesting characters design.Yes the sound and ambient is brilliant but I think it should be more unique tha it used to be.
Obviously,the story is edited for short version or make it easy to make it smooth.
I think the original story is very interesting because we have seen many strange tribe but their's power is still secret.
When I watched this movie I think it's good than I think but not the best.But I can't refused that it have many things look interesting and it'll so good if they will release 9 Satra part 2.
The story itself have many deep dramatic scene but they keep it in a "children's movie" way. I hope to see more detail and more dramatic in this animation.
