What a terrible, terrible waste. A-1 took a fascinating story and utterly ruined it with terrible production. The animation after episode four took a nose dive into low budget garbage and took the entire series down with it. It was nearly perfect in episodes one through four. From five and thereafter, though, it just becomes depressing.
The first anime to come along with such an interesting story since Madoka gets ruined by trash can art.
A part of me died with the art in this series.
