^The anime of part 3 is probably better, since it expands on some moments in an appropriate manner, whether for character exposition or humour, not to mention some excellent tracks and adding a foreshadowing of part 4. It also boosted the writing quality by a small amount by erasing a few plot holes (eg. Silver Chariot only removing it's armour once in the manga). Part 3 is an alright part, being one of the more entertaining ones and having an OK character cast, though the repetitive nature is somewhat annoying. It is, however, made easily tolerable by the abilities and characters allowing for some interesting strategic fights.
As for the OP, JoJo's Bizarre Adventure ranks amongst my favourite manga/anime. Part 2 was my personal favourite in terms of entertainment, though the best written part was either 6 or 7. Also, yeah, Joseph is hands down the best JoJo (though Josuke's a definite second).
There's a lot of reasons I love the series. I'll provide a short list for now:
- Hokuto no Ken tributes in the early parts, as well as a small one in Part 6.
- The originality of each part focusing on a new protagonist and setting, something that most manga find hard to pull off, especially a Shonen series.
- Iconic poses as well as extravagant colour switches (mainly in the anime for the latter). It's so damn Fabulous.
- Many iconic moments ranging from quotes, battles and practically anything Dio does.
- Strategic battles, mainly those in Parts 2 and 6. The level of strategy and intelligence going into these superpower battles is easily on par with Shonen acclaimed for being strategic works, such as FMA and Hunter X Hunter.
- The cast of each part shows a lot of diversity, especially with the villains. Kira and Pucci are easily some of the most original villains in Jump.
- It's anime adaptation is one of the few series to stand on par with it's manga. In some ways, it even improved on it, since there were a lot of things that I didn't notice as much when I first read the manga. For example, Part 1 felt a lot more exciting, with the themes of family and opposing ideals resonating a lot stronger than the manga, which seemed like a mediocore Shonen plot-wise when I first read it.
