A classic and rare title for us stateside, I'd heard it mentioned and described and summarized for years. Got a DVD copy for the archives near the end of last year (went by quick and thank God for that) so I could finally see for myself what was so Otaku about it.
Overall a nice watch with an odd premise. Animated fictional account of a fan's ascent/descent into otakudom mixed with live action segments in a documentary style. The only thing that drags it down is those live segments. I enjoyed the anime skits and I could readily spot which character was inspired by my manga-ka hero, Kenichi Sonoda.
Funny in a self deprecating way, truthful without pointing a finger in your face and yelling, "YOU'RE SICK! GROW UP!", and for an older project I don't think it has aged too badly.
I'd suggest it for the completionist collector of genuine anime geek stuff, and applaud anyone who gets the gang together for beer and a viewing party. Hey, that sounds like a great idea...
