Lain

I was browsing for a rental, and picked up a disc of a television series. The owner started talking.

Owner: So do you know what this show is about?
Me: No. Is it any good?
Owner: Yes, I liked it.
Me: What is it about?
Owner: Well, I won't spoil it for you, but it starts like this...what happens when one of your friend commits suicide? She sends email to you.

I found his description of this premise far more interesting than the show itself.
