my middle sister watched the 1st 2 Gokusen series . She did watched the 3rd season but she gave up 1/2 way because it's exactly the same time you're watching 3 times in a row @_@
that's what she said , not me , I'm just the messanger
usually the 1st season of a drama's the best & that goes for movies & sequels but of course there're certain exceptions like Spiderman 2
