Yeah, I only saw the first three episodes of EL, only liked the first one.
I saw all of Ergo Proxy, thought it was badassed, but there were two problems with it: 1, it seemed to suffer from the "monster-a-week" syndrome through episodes ... 17-20, maybe... and the ending seemed to be at a different pace than the rest of the story, even in terms of the themes (good nonetheless).
SEL, however, was GREAT I sadly only saw the first few episodes of Texhnolyze, and thought it was great as well.
Oh, and FLCL is a real trip, although it's very short. As for movies, I'd suggest Mononoke, Ghost in the Shell 1 and 2, Tekkonkinkreet, Paprika, and a few others... As this anon >>13272481
said, NANA is pretty good (hell, my gf gave me unimaginable favors for finding the live action movie for her, if that suggests anything to you; it's got a distinct chick-flick feeling, but it was pretty good anyway).
