It's sad to say, but haven't still understood Gokusen success. I had watched the first season and it was bad. I had watched second series and it was better (look: the cast). Today, I've finished third season and there was hopeless again. Maybe, I'm too critical, it's only a school, and there all days look the same. Maybe it's becaused od actors, because I don't know the youg boys well. In my opinion, everything should be finished after second series.
