I never really realised before, but the introduction of stands really just turned Jojo into a villain of the day anime. I don’t really remember that being the case during the first two parts, but I got through all of parts 3 and 4 without really noticing it. So I can’t really say I mind.
The last handful of episodes of the series have primarily been there to introduce us to the gang, their personalities and their stand powers. Aside from that though, It’s been about fighting off the hoards of enemy stand users. Standard fare.
