Going in order through the Jojos, this is another twist on the formula, breaking away from having a real Joestar and having a weird half-ish hero by way of villain. The actual action unfolds into a similar chase like Part 3, but all throughout Italy and full of morally questionable folks. A wannabe mafioso isn't a very typical protagonist, and it's unfortunate that Giorno has even less personality than Jotaro because he could've done more with his motivation and the way he fights the structure from within. But instead, he is a stoic badass that barely talks after the first 15 chapters and is too strong for the plot (for the 3rd time in a row a Jojo is BUSTED in combat).
The art has cool cut-ins to show reactions to the insanity that unfolds, which is a nice touch for this part, but the art is a step down from the last two in terms of coherence. Characters are sort of interesting, but also less endearing than Jotaro or Josuke's posses (save for Mista, who is great).
If you want the series to be more fashionable and more people to melt into horrible puddles, then this might be your favorite part! For me, I'm not going to look back on it too fondly.
