Raise your hand if you know what the term, "otaku" means. Not too many of you, eh? Well, for those of you with your hands raised, keep reading. For those of you who don't have your hands raised, you may as well stop here because you probably won't give two shits about what this article has to say.
Moving on...if you haven't already heard of Genshiken, you need to torrent that shit and get to watchin' because this is the most otaku-tacular anime you'll ever lay your obsessed little eyes on. Every second of it will remind you of your friends and how otaku come in every shape and size, even the type that denounce their own kind. It's basically about a club at a Japanese college devoted to everything otaku: music, video games, anime, manga, doujinshi, yaoi, cosplay, etc. I probably relate the most to Ohno-san as she loves cosplaying as much as I do! Granted I don't have the resources to cosplay as often as she does, but I would if I could! You'll probably see a little bit of each character in yourself, however, as they're all so diverse (except for the chairman, that guy's just fucking weird!).
To save you the Wikipedia look-up, the first season is 12 episodes long, there's a 3 episode OVA, and the second season is also 12 episodes. Unfortunately, that's all there is at the moment. There's still chance for a third season, however, since Genshiken 2 finished airing in Japan around X-mas of 2007. Of course, any idea of a third season is merely rumor and speculation...
But a girl can hope!
