(POTENTIAL SPOILERS)
I've watched all 5 parts and now starting Stone ocean, Tbh I knew about the Hype of Jojo, and just started watching after I finished Demon Slayer, and I can say, it was the same level as part 1, it's just I wanted to Finish Demon slayer faster.
One of the only reasons I continued with Jojo is because I heard it gets insanely good later on, which is what I got.
Phantom Blood: Really well-done part. It may not be as interesting as the others but it sets the entire story so well, it's like the therapist friend is not being the focus and mainly the side character but sets it up for all the Main Parts of Protagonist to really shine well with back story.\
Also, the Best Waifu Speedwagon is in his prime.
Battle Tendency: Not only does it have the best Jojo (In my opinion) and the best opening, but it also has the best memes and the best name, Battle tendency, Battle tendency! Its really fun to say, Although it's at the good parts yet, Battle tendency is a solid part. It's on the same level as most popular animes and that says A LOT.
Stardust Crusaders: Finally, we get to the good stuff, Stands.
Also here we get the politest my favourite character JoBro Kakyoin, and Jotaro Bridge, the best thing in the series.
Even though there are going to be like so many parts in the future, to me it always feels like Jotaro is going to be the Main Character, he was the protagonist in Stardust Crusaders and really helped out later on.
Polnareff, Old Joseph, Avdol, Kakyoin, DIO, Iggy, they are well written characters and the Taro Cards literally top it off. Personalities are based off them and it really does fit the Eqyptian Vibe honestly.
Diamond Is Unbreakable: HERE, Is arguably the BEST part. Yoshikage Kira is such a good villain, and the Bites the Dust arc is one of my Favourites. Ofc Koichi being the Reliable man he is goes on to have a Yandere Love interest and still stays very Chad about it.
Actually, the Yukako and Koichi storyline is my favourite out of Part 4, and the amount of friendly every day stands in this part is what makes it so good. It is like a break from the ads or the overwhelming amount of battles in Stardust Crusaders. To top it off you have the final fight, which seems so realistic and kind of makes Hayato the Main Character. Only Problem with this part is the fact it took a couple episodes to determine the main antagonist but its such a good part, all of the 100 episodes to this part was worth it.
Golden Wind: This is the other part people may say is the best part. To be honest I really enjoyed this part its insane. Though I spoiled literally the entire storyline I feel like I enjoyed it more so I didn't have to spend
half of the storyline wondering where time went. I said to myself I would only watch 1 episode a day of Golden Wind.
I finished it in a Week.
That's how good Jojo parts can be, trust me, it's so worth it.
In the Final Arc of Part 5, it felt like there could be a Golden Wind Part 2, I just needed the aftermath after Giorno defeated the main Antagonist.
That's my only Dissatisfaction.
Stone Ocean: Haven't Finished it, Jotaro is still basically the Protagonist.
