I'm looking for anime with a story that has at least somewhat of an
Existential feel.. something in the same league as the following (yeah, I know it's still kinda broad):
Evangelion
Naruto
The Melancholy of Suzumiya Haruhi
Noir
.hack (Sign and Roots)
Paranoia Agent
Madlax
Welcome to the NHK
Cowboy Bebop
Narutaru
Boogiepop Phantom
Serial Experiments Lain
Any recent and preferably unlicensed anime I'm missing that sort of "fits in" with these in having Existential themes?
