Well, he was always silly, even when he was the hero.
Problem is he used to be a badass. Used to beat up physical gods with a bola. Now he's the weakest guy on the team.
I mean, okay, Ripple doesn't work on Stands. But it should still work on the users right? Most of these fights should be ending with Joseph punching a Ripple into a guys face.
Yeah, this is definitely a problem I'm having with this entire arc. The characters are SUPER stupid and gullible. Jotaro seems to be the only clever one in the bunch, and even he tends to let the badguys do what they want for WAY to long before finally taking action.
If this is the most popular arc of this series, the final battle must be amazing or something.
