I like Part 1 as well, it’s not my favorite but it’s still a great way to introduce the series. I can’t disagree with you more on Part 3 though, I love the whole globetrotting adventure. Not to say that each part lacks flaws however, I still hate it that as soon as Avdol comes back that Kakyoin gets taken out until near the end of the Part. But like the title says, all of Jojo is better than 99% of manga.

Am I the only one who really likes part 1? The relationship between Dio and Jonathan is almost mythical in execution, and I find the mix of classical horror and fighting anime great.

My least favorite is part 3. Weak characters (relatively), boring stands (relatively), excessive Monster of The Week, and simplistic plot.
