Abenobashi Mahou Shoutengai - Watched the first episode like 8 years ago and it was fairly entertaining. Can't say more than that though since I can barely remember anything.
Angel Beats - Loved the show but I think it's bordering on the everyone has watched it category. Not a bad choice at all but I think it would be better to give a slot to something else.
Ano Hi Mita Hana no Namae wo Bokutachi wa Mada Shiranai - Too recent
Asura Cryin - It's entertaining though a bit convoluted. My biggest concern is whether or not people will get through the first series which is mostly just what the hell is going on. Asura Cryin 2 is stronger overall and brings most of the things introduced in the original together.
Azumanga Daioh - Great laughs and it's been a while since it's been shown in full in the club. A safe bet.
Darker Than Black - Technically we did watch this 4 years ago but never to completion so you could try it again this year. No real strong feelings either way though.
Dennou Coil - Never watched it but L loved it and really how many things does he actually like?
I'll let him explain.
DuRaRaRa!! - Never watched
eX-Driver - Never watched
Futurama - Although I'm a huge fan of the show I don't think there is a point to showing this since it's easily available to watch on Comedy Central.
Ga-rei Zero - Beautiful action and drama show. Would recommend just for the first couple of episodes themselves but everything afterwards is just as intense.
Gankutsuou - A sci-fi twist on the Count of Monte Cristo. Very, very strong thriller drama.
Genshiken - Watched this 4 years ago though we never finished Genshiken 2 (Sorry about that). Could possibly watch. My only concern is how hard it would be for newcomers to anime to understand jokes and references in the first one since even I had trouble with that.
Ghost Stories - I don't think my body can handle seeing multiple episodes at a time.
Grenadier - Never watched
Hanasaku Iroha - Too recent.
Hidamari Sketch - I personally enjoy this but
like miki_sei said, I doubt there will be enough overall appeal for most people so I vote no.
Higashi no Eden - Never watched
Kare Kano - Never watched
Kimi ga Nozomu Eien - Fantastic romantic drama series with high chances of tears and rage. Would be great for the club as it would generate a lot of discussion amongst members and occasional "no yous." At least for me that's why I prefer us as a club to watch entire series versus sampling a ton of shows like most other anime clubs. Also if this is shown you
MUST show the OVA afterwards to give the other side justice and create more rage between the two factions which will develop.
Last Exile - Very good adventure series. It's not the type of show we normally show so it'd be an interesting way to shake things up.
Macross Frontier - Exciting dogfights, catchy music and triangles. Would fit nicely in the action slot.
Mahou Shoujo Madoka Magica - Too recent
Michiko to Hatchin - Never watched
Minami-ke - Watched it
Spring 2010 and it would be strange to show the sequels since they come literally a few days after the original finale so I vote no.
Moyashimon - Pretty fun dicking around and interesting characters so possibly. I only suggest you don't show it at the beginning or end when people maybe eating or getting ready to eat.
Natsume Yuujinchou/Zoku Natsume Yuujinchou - Strong series in its own regard but I think this has great appeal especially for female fans.
Nogizaka Haruka no Himitsu - Liked it overall but the only really strong parts are the beginning, ending and a few middle episodes. The sequel...Let me put it this way. I don't even remember what happened. If you decide to use this, only show the first series and let people watch the second on their own time.
Seto no Hanayome - High energy laughs. May possibly be too overstimulating.
Shinryaku! Ika Musume - Too recent
Solty Rei - Never watched
Spaceballs: The Animated Series - Never watched
Speed Grapher - Never watched
Trigun - Never watched
Vandread - Never watched
Welcome the NHK! - This is THE show when it comes to NEETs and hikikomoris. It starts off mostly comedic exploring the stranger sides of otaku fandom but gets progressively darker as it delves deeper into the darker aspects. Would be a great fit for the club.
