I'm not minding the stands so much. I like that the user takes damage if his stand gets "hurt". It's better than Gaara, as far as the plot goes. If Gaara's sand arm gets cut in half, Gaara just makes a new one. If Jojo's stand's arm gets cut in off, Jojo loses an arm. I can live with that. Especially since it means users can attack two targets (and so have to defend two targets).

How did what's-his-face's art attack work, though? Was that Heironymous Green? Or some other power?
