Hi there ^_^x

Hope you are doin well, here are three that can 
be regarded as being cerebral and on the somber 
side in a way.
Neon Genesis Evangelion, Serial Experiments 
Lain, Boogiepop Phantom. So you have to like 
that kinda stuff off the bat to appreciate them. 
Hope this adds to your list, take care and happy 
lainning!
