Based on the manga which I haven't read or watched the anime, the whole story/concept is very cool and there were some great scenes and parts which sparked real emotion and left you wondering what would happen next but the development and revelations felt rather dry in the sense that the plot was drawn out quite a bit and left you yawning at times rather than being on the edge of your seat, the anticipation was there but it just wasn't enough to make this show magnificent. That being said the character relationships were very compelling, there was a real sense of friendship, overcoming and determination. Overall a very enjoyable watch but don't set your hopes for anything magnificent.
