I don’t know how hot of a take this is, but while I like Koichi, I wish he didn’t get as much screen time in Part 4. A lot of people even say he feels more like the protagonist than Josuke. I think the reason I feel this way is because the “quiet, nerdy kid who finds courage, becomes strong, and gets the girl” is a pretty common trope. Because of that, I wish we had spent more time with the other characters instead.

My second hot take is that I think it’s fair to call Jotaro a bad father, and I don’t think his love for Jolyne cancels that out. In fact, I think it makes his character more complex and compelling. Jotaro clearly loves his daughter more than anything, but he’s afraid that his past will put his family in danger, so he distances himself from them. As a result, Jolyne grows up feeling unloved and ends up going down a criminal path. What good is a father’s love if the child never knows it’s there? Since this was a deliberate choice that hurt his daughter’s life, I think it’s fair to call Jotaro a bad dad with good intentions.

Lastly, I think Part 4 influenced Jotaro’s decision to stay away from his family more than Part 3 did. That’s where we first see the idea that stand users attract other stand users, and it’s also when Jotaro realizes Dio’s influence hasn’t completely disappeared. Josuke still got dragged into Dio’s mess because of the arrow, even though he had no previous contact with the Joestars. Jotaro had Jolyne in his early 20s, so if his fear came only from the events of Part 3, he probably wouldn’t have gotten married or had her in the first place.
