Emotes are gay. I'm a retard in this thread. Just ignore it.

Mushishi and Denpa Teki na Kanojo are other ones, but in both cases they are under-spoken rather than underrated. I think that's the same case with many of the animes mentioned in this thread because
underrated would imply that people who watched it didn't like it, which is wrong in most of these examples.
Animes mentioned in this thread: FLCL, Eureka 7, Serial Experiment Lain, Mushishi, Monster, Claymore, Welcome To The NHK, Baccano, Golden Boy and Read or Die. I have have heard nothing but good things about these animes, especially Golden Boy, Welcome To The NHK and Monster. And I've only watched 4 out of these listed and I have to say they were all very good.
Just because any of your friends haven't seen
(that anime) yet doesn't mean it's underrated.
