I'm looking for anime like:
Xam'd, Book of Bantorra, Lain, Ergo Proxy, Texhnolyze, Zankyou no Terror, Ghost in the Shell, Psycho Pass S1, Death Note, gargantia, code geass, fma (2003), darker than black, soul eater, btooom, shinsekai yori, Ghost Hound, Haruhi
They are all very similar to each other, though very different at the same time. I think the most obvious characteristic between all of them is that they can teach you something about life.
