If you want thought provoking material, Anime is a goldmine. Steins;Gate, Neon Genesis Evangelion, Ghost in the Shell, Psycho-Pass, Shin Sekai Yori ....... It's a long list. Since you love Serial Experiments, I highly recommend Evangelion, Boogiepop Phantom, Paprika, Perfect Blue.
Thanks for reading it dude! Yes im a big fan of anime,watched the above which you mentioned, recent was shin sekai yori. Im glad you mentioned about it cuz its the most under rated and deep philosophical one
NGE is awesomme, paprika n perfect are damn good. I still need to watch Boogiepop phantom.
and you can reply to this, if you recently found any good animes
Youjo Senki, Texhnolyze, Harmony, Empire of Corpses,Ergo Proxy.
These are not very philosophical but has some of the best atmosphere and immersion I've ever witnessed: Shiki, Another, Higurashi No Naku Koro Ni (If I reveal what genre this anime is,that would be a major spoiler. Go blind and finish the first season. Don't look it up anywhere)
Also Try Cronenberg's Cosmopolis. It's my favorite of his movies.
Also try One Punch Man and Fate/Zero and Unlimited Blade works(Season 1 isn't very good but the rest makes up. Last bits are almost euphoric.)
