CASSHERN SINS (2008-2009) is a dreamy, post-apocalyptic sci-fi anime, with heavy melancholic vibes and thoughtful philosophical undertones. Soft, abstract, moving...with bouts of fluid, vibrant action, this series is really different from the everyday cyborg / robot / mech series out there. It has such a powerful although abstract story, and leaves lasting impressions long after. Powerful and poignant. Nostalgic, as well.
"Casshern is a robot that wakes up to a world in Ruin, a dark plague brought on by his past sins, the killing of the being Luna. He has no recollections of this sin, but everyone he crosses paths with hold him accountable. Somehow he must right his wrongs and find redemption for his sins."
Overall, this was a haunting series. The storytelling is sad and mesmerizing, though quite vague. It often leaves the viewer to use their imagination. Artistically, the anime is quite vague as well; it's abstract and sometimes minimal, which works to its benefit. The music is very stirring and emotive, but suitable for the overall atmosphere. The character development and world building really made this series strong and memorable. Casshern's journey for redemption is moving.
