Gokusen is the female onizuka-ish, there I said it.
I love digging from the garbage pits of hell olden years of anime shows that I can watch, without all the complexities of modern time anime, there's a sense of innocence and non-try-hard writing that makes me chuckle.
Writer: And then, he doesn't remember anything that happened before the car crash, muhahaha, they would never see this coming.
(Not spoiler for the show, just a tragically common trope in old anime)
Gokusen is nice, but I can't fully judge until I've read the manga, because the anime feels like a sample, but I consider anime that makes you want to view the original material successful.
What to expect:
It's old, it'll tell old stories, nothing shocking, but nice pacing.
Cheesy, feels good, sort of funny, and nostalgic.
Absolutely love the lead. She just isn't something you see often, or ever, she's not a trope or fetish.
Enjoy it, I'll probably edit with a review of the manga.
