Well, there's not really much going on to talk about right now.
They introduced 26 new villains at once. They're having Stand battles with our 80 pre-existing characters. None of the new abilities are particularly "Oh shit! That's really clever and novel." Kurotsuchi just used Itachi's Izanami.
I guess the only real development is our main villain is actually after the "Soul King". But it's hard to care since we don't even know who that is.
