Casshern Sins is one of those great series that is not for everyone. The artwork, score, action sequences, and voice acting are all top-notch. However it is a very moody work, full of angst, rage, and melancholy, pensiveness and hope. What's more, it is very allegorical as well: it is obvious it is about something but it's tough to say what it's all about (and reminiscent of Evangelion / Serial Experiments Lain in that respect). Personally, I am fine with moody and mysterious animes and rate it way up. If your taste is for something straightforward then you may find Casshern Sins a disappointment.
