Let's be honest, the actual content of this anime isn't the greatest. But that isn't the point of the anime. Even though the story itself feels short-lived and not very developed, the art and animation remains beautiful without a doubt. In almost every aspect in terms of animation, it has went above and beyond. But for actual plot and story, it was very short and definitely would have done better if more episodes were added. Worth a watch for the art and animation, but not much else.
The characters were all laid out and had good story behind them all, but it felt as if not enough time were spent on each persons story to have the viewers (us) really care much about them. We will know their backstory, but not really "connect" with the character themselves.
This anime is basically an excuse to make amazing and awesome art and animation. The best I've seen in a long time. Focuses primarily and how you can view the world differently and how beautiful things come from everyday life and so on and so forth.
