One of the things I laughed out loud at was FF's "healing". I know the reason for it - you want to up the ante and decapitate people or whatever but at the same time have a get out of jail free card. It worked with Josuke's ability and to a lesser extent Giorno but FF was just ridiculous. Oh yeh bro let me just plug up your wounds with plankton.

Jolyne stitching shit together made a bit more sense.
Might be controversial then but Part 4 might be my favourite so far (though I've only just started Steel Ball Run). The characters can be a bit hit and miss and Josuke probably isn't top tier JoJo waifu but I just really like the smaller Morioh setting, the stands were pretty creative and interesting and Kira was straight pimp. Dude just wants to live a quiet life, clip his nails and occasionally choke bitches. Can't hate on that.
