I am a very big jojo fan. However I am an even bigger Part 7 fan.

It's a well known fact that Araki at first wanted part 7 to be a part of a different series and it shows quite clearly. There is a big shift in the tone and pacing compared to part 6.

Story: 9/10
The Story stays entertaining all the way through. The horse racing at the start of the part would be serviceable enough on it's own but as the story progresses it gets much much better. "Who shot Johnny Joestar" is still the most confusing stuff I've seen in a manga in a while.

Art: 9/10
Jojo art is interesting because it isn't necessarily the best looking I've seen however Araki's ability to adjust his style to the tone of the manga is outstanding. The close ups in part 7 are probably the best in all of jojo and the stand designs definitely reach their peak in part 7 too

Character: 10/10
Part 7 has the most well written characters in all of jojos , and that's not even a hot take. Funny Valentine is my personal favourite character in the whole series and Johnny is a close second. Characters in shonen are usually clear cut as either "good guy" or "bad guy" but now that part 7 is a seinen the morals of characters are allowed to be more flexible allowing characters such as Funny Valentine and Sandman to be villains whilst not really being evil

Enjoyment: 10/10
The comedy in part 7 is godlike. The interactions between Gyro and Johnny are so funny and even Pocoloco has some great moments. The action is riveting and the story is gripping.

Overall: 10/10
I would 100% recommend reading part 7 and reading jojo parts 1-6 just so part 7 has more weight behind it. Truly a masterpiece
