Graffiti of Otaku Generation

A unique look into Japanese fandom, set up as a mockumentary. Its biggest feat is that the film still comes off as genuine and heartfelt, even though it doesn't really spare its subjects. It's a very solid introduction to otaku culture, it contains many references to the birth of Gainax (the studio behind the film and best known for Hideaki Anno's involvement) and the comedy is spot on. It's one of those "better experienced than explained" films and even (or maybe especially) to this day, it remains surprisingly accessible. A true anime classic.
