Review of Casshern Sins

I think that this anime too vague for the length of the whole show. If it had less episodes it would have been fine, but far too many episodes are used to set the atmosphere or for random encounters with one-time characters that serve for either that or a philosophical insight. In the end this falls flat and dulls the experience, because this is a singular storyline for which far too little details are given about throughout the anime and it stays vague nearly until the end. I believe that in this Casshern tried to be like Kino no tabi: The beautiful world, but unfortunatelyfailed to deliver.
(unlike Casshern, Kino no tabi could allow itself to be slow, vague, and only philosophical because that was the nature of the story - there is no singular purpose and every episode is for itself, a new experience)
Also, I didn't appreciate how for a lot of (side) characters the motivation behind doing the things they did was not properly explained at all.
The raised philosophical question was no news to me as well, though I understand why people can appreciate it through this anime.
All in all, I did enjoy this show a lot of times, and I really like both Casshern and Lyuze.
