I am currently watching ghost in the shell stand alone complex 2nd gig. I like the franchise. The movies are good as well.
I only care about stuff that has got some artistic value. Some other anime that I have watched and have a high opinion of are Mushishi, Texhnolyze, Haibane Renmei, The Tatami Galaxy and Serial Experiments Lain. Ergo Proxy also tries to be deep but gets a bit too ostentatious for my liking. Death Note is quite shallow and superficial.
