Hmm, FLCL is more stylish than anything, I think.
I do like stylish stuff too though. Love Samurai Champloo for mixing samurai and hip hop and doing it well.
Never watched Cowboy Bebop. Like the jazz inspired music though. "Tank" f'ing rocks.>>12382131
Because this was bugging me and I don't need to sound even more elitist, I'll explain my take on it (or otherwise the general belief in its themes)
SE Lain deals with the Internet and how it fundamentally changes communication between people and interpersonal relations. It deals with the idea that the Net is "another reality" and asks whether or not "the Wired is an upper layer of reality" or "more real than reality itself"
In a way, maybe that's kind of true now. Anon is perhaps the ultimate example.
