There's been a few recommendations already for Serial Experiments Lain, but whilst I did enjoy it, for my money Texhnolyze by the same creator is absolutely incredible (and much less discussed). It's very slow going though, particularly at the start, but I still think about the last several episodes on an alarmingly regular basis (having watched it years ago). I also recommend Now and Then, Here and There: a fish-out-of-water fantasy show in which the main character acts like a stereotypical comedy protagonist but the world he gets transported to is an absolute wasteland ravaged by war and environmental degradation. Unsurprisingly also not a light-hearted watch.
