Great Teacher Onizuka was a great anime. It had a great character that was able to do anything that was thrown at him. However, that show must have taken inspiration from Golden Boy, because Kintaro is able to do ANYTHING that he needs to, all for the sake of the many girls. Anyway, I think that GTO was inspired by Golden Boy because GTO uses the same style of exaggerated art and perverseness.
This show has a great main character, the music is epic, and each episode has its own perks that makes it very memorable. However, this series is very short, but good! In fact, it it were any longer, then Kintaro Oe would no longer be the traveling 25 year old scholar, but probably the 50 year old scholar, because something this great can last that long!
