What a ride! This part is clearly the most mature so far. Not for the sexual content, but for the characters, especially Johnny. He really stands out as the more real of the Jojos. Don't get me wrong, all other Jojos were great, but they all were absolute winners. Only in Johnny we see true desperation and even some malice. He acts as a loser in many occasions, he is secondary to Gyro in most of the initial arcs, he can't even defeat Dio. He isn't an embodiment of honor as part 1 Jonathan, he was a jerk before being crippled. He really grows as a character through the story, but he never stops being a flawed human being. And thats what makes him more real, because unlike Jotaro or Giorno, real humans are flawed.
