Lain still has a huge fanbase to be asking the question "does anyone even remember it"
Yes I remeber Lain it's an amazing anime... It is by far one of the greatest forms of any media I have had contact with.
The plot is beautiful and in it's own way (like most sci-fi) a believable look into a grim future we might build for ourselves.
If I had any complaints at all it would be that it had moments where I wish they would have built their characters a bit more... Or just not included them at all.
I think that it will stand the test of time, if only for a small crowd....
