As the subject implies, I'm interested in NEET media: films, books, anime, whatever.
We all know about Welcome to the N.H.K., so let's just get that out of the way right now.
For films, I can offer Ima, Boku Wa:

The characters don't necessarily have to be NEET in the true definition of the word, but if that's the case there should be NEET-centric themes, like isolation, depression, anxiety, and other such negative things.
Since NEEThood isn't all bad, media portraying happy NEETs is welcome too.
