Words Of Wisdom on 12 February 2009
Ghost in the Shell is hugely overrated in terms of internet presence. Serial Experiments Lain was aired on TV (TechTV's Anime Unleashed R.I.P.) so it has a pretty widespread following. A friend says it's her favorite anime of all time...
That's my definition of underrated too Torillian. And Baki the Grappler is a great example of an underrated one (have you heard of it?).
Iriya no Sora, UFO no Natsu is a good example of an underrated OVA but OVAs are a bit too easy to do. Gatekeepers might qualify but it was somewhat big at one point (not so much now though). The problem is that a lot of popular anime in Japan weren't very popular outside of it. Magic Knight Rayearth is a good example that got a full series and its own line of games.
