While Jojo part 5 is a step back from part 4 in my opinion, it is still good.

Golden wind is honestly the black sheep of the series. You could go from Diamond is Unbreakable to Stone Ocean, and nothing would be lost. Golden Wind feels completely independent in that way. There is some connection to previous parts though, because our protagonist is the son of Dio and Jonathan. While the story does take advantage of his bloodline sometimes, Giorno Giovanna is pretty basic, honestly. This is alright though, because our Jobros are pretty cool, especially Bruno. The only one that is flat is Fugo, because an arc he would've been very prominent in was scrapped, which is disappointing.

In some ways, Golden combines the best parts of Stardust Crusaders and Diamond is Unbreakable. Combine the small scale of part 4 with the road trip structure of part 3, and that's a generalization of part 5. The plot is also much more involved than in part 3. Things actually happen, and some battles feel really important. Even if the plot was nonexistent, these battles are so great it wouldn't matter. Golden Wind has the best battles of any anime or manga ever, which isn't something I say lightly. The stands are great, with the only complaint I have is that Giorno's is too similar to Josuke's.

Another thing I like is the theme of part 5. Jojo parts rarely have themes, and are just enjoyable stories. Golden Wind has a theme, and that theme is relationships. Giorno often relies on others to truly win, and those people rely on him. Even the villains rely on each other. Except for the main villain, Diavolo. Diavolo wants to eliminate all the connections he has with the outside world to ensure his domination. Because of this lack of interaction with people, he creates an alternate personality to stave off the desire for love and friendship all people have. However, Giorno and his team continue to prevail because they have each other. This theme is why I love Golden Wind.

One problem I have is that the ending feels a bit like a deus ex machina, and raises questions about the next part (I won't say anymore because spoilers).
One last thing is that King Crimson is confusing in the manga compared to the anime. I guess the anime is the best way to experience Golden Wind.
