Casshern Sins

Casshern Sins is probably one of the most philosophically heavy animes to date. It focuses primarily on why we live and for what purpose. This is done through a barrage of small stories throughout the series. The main story has a somewhat coherent plot on the same matter, but it often fails to explain what's going on and assumes you can make out details through inferred explanations (found myself rewinding here and there to catch various points).

The worst thing I can say about the anime is it takes about 3 episodes to get going. Despite its flaws it has an amazing soundtrack, VERY memorable characters, and some truly spectacular stories to tell. If you aren't into heavily philosophical concepts this anime is not for you. For those who enjoy this kind of thing, you wont find anything quite like this out there.

Please note that I haven't seen the originals, so my review is from a fresh perspective.
