I found the animation to be quite good, not at all horrible. I wont be doing any why no Kyoani since that has all been done before. But, I'm not very happy with the style transitions as I'm a huge fan of Itaru's work and see that most of it is lost. Na-Ga's style is also somewhat lost in the eyes.. The style isn't horrible like Toei's version XD. I guess I will have to wait and see what an episode will look like.
Thanks Kaisos for comparison
