I absolutely hate 90% or more of anime and cartoons, especially modern stuff, but love the other 5-10%.
Beyond Ghost in the Shell and Samurai Champloo there is Akira, Neon Genesis Evangelion, Cowboy Beebop, and anything by Hayao Miyazaki to name the classics. Basically if it was written for adults and isn't half soft porn it's usually at least semi decent, but like all creative content it can fall anywhere on the normal curve of quality. Same goes for the quality of all the adult swim shows, but I can't really be objective about those since they were a staple of my college years and everyone from stoners to jocks watched them almost nightly.
The craziest movies from asia aren't animes anymore though, check out Oldboy if you want something slightly insane and very disturbing. I could talk for hours about TV or film in general though so I'll shut myself up.
