Story was rushed. They forced a whole arc into six 20 minute episodes.
Seems like everyone is playing on the whole ‘Man with nothing to live for helps little girl in her adventure” to death.
Fight scenes were nothing to look at. The last fight looked like a boss fight out of a video game.
All in all, this was boring. The whole appeal of a black samurai was quickly nulled. Power was never truly explained. How was everyone manipulating this energy and where did it come from.
The writers should be ashamed of themselves. It seems like they watch a lot of anime and thought they could create one. They were wrong.
