Gokusen is one of those manga series' that you start off being not so sure about, but end up finishing before you even have a chance to blink. There are some cultural references sprinkled throughout the series, but not enough to distract the reader. The teacher, Yamaguchi Kumiko (a.k.a. "Yankumi") is a funny, honest, highly respectable-type character that I often find myself looking for in most comedy-type series. I really like the fact that although she's tough, she's not invincible (which is awesome), and she really gives a crap about the people that most others are all too eager to toss aside.
I was able to get my hands on the Japanese quite a few years back and, like many others, was not too impressed with the art work. But the mangaka does improve the character design quite a bit towards the middle of the series. The funny thing about that is...by the time she did, I was so into the story that I hadn't even noticed. LOL.
It's definitely worth reading for those who aren't too reliant on romance (there are a few VEEEEERY subtle encounters throughout the series, and the specials allude to more romance) and just want to read something that's good and makes you laugh, then I highly recommend this series.
Not a fan of the dramas and the movie though...although Nakama Yukie does bear a striking resemblence to Yankumi. It's almost kinda scary...
Also, it it just me, or does anyone else believe that
Wada Kyousuke is Kumiko's dad? I know what he told her himself, but...
Anyway, yeah. Great series here.
