There are 8 parts to JJBA but I'll only be talking about 7 (cuz i only got to 7 ;) ) but this is a warning that this chapter is gonna be really long since I'll be talking about each part.
!!ALSO ONCE AGAIN THERE WILL BE DEATH SPOILERS IM SORRY!!
\---------------------------------------------/
Started? - Part 1-7 Yes
Completed? - Part 1-6 Yes Part 7 I'm halfway through it
Plot opinion - When I first started watching JoJo I was very confused as to why the main character died so soon, since usually when your watching an anime and the protagonist gets in a dire situation you already know they won't die... especially if there's a lot of episodes still left, why would the main char die? That means the anime would end...right? Boy was I wrong. The plot itself changes during each part, I can probably say the part i liked the least was part 2, for personal reasons.
Character Opinions - I really enjoy the concept of the Joestar bloodline being passed down throughout each part, just when you think "That boy/girl has no way of being related to Jonathan (the first JoJo)" the author finds a way to throw them in in the most unexpected but very real way. When I say real, I mean families aren't created by people marrying, having kids, those kids having kids, and so on, no.. some side hoes were included.
Do I have any ships? - The ones I ship the most are Jonathan and Erina They are by far the most wholesome couple in the anime and I live by that.
Key Likes - The Diversity!!
Key Dislikes - I mainly didn't like how some of the joastars were forgotten. When I say "forgotten" I dont mean the author threw them in for a short period of time then suddenly they stopped showing up. I mean how they would be significant to their part then nothing else would ever be said? For example, part 4 Josuke. since he was young I kinda figured there would be some kind of time skip at the ends where he is an adult or something but no....he doesn't really show up after he beats his main villain. And I say this because take Joseph and Jotaro for example. Even though they weren't extremely important to the other parts they still made it in there. Hell, Joseph made it to 2 other parts and Jotaro was in 3!
