I'm looking for something maybe kinda psychological, philosophical, whatever. I know a lot of you guys hate that stuff but I'll just ignore the SAGEs and skip to the good answers.

I really liked the existential themes in Big O and thought they were done a lot better than other similar works. Apart from EVA I can't think of anything else which is why I want to check out something along those lines.

Obvious suggestions are Monster and Serial Expirements Lain. What can I expect? I'd like it to be quite "dark" too, visually as much as much so the themes.
