The thing about Part 8:
-The wall of eyes hasn't been relevant in the last 3 years.
-The man from Josuke's awakening has never been hinted at and has been completly forgotten.
-Josuke no longer has any personality qwirks like he used to such as his extensive vocabulary, laying under matresses for pressure.
-Every single time they finish beating a group of rock humans, an even MORE SECRET group of rock humans that the last 2 didn't know about shows up.
-Everything that was set up with the Higashikatas has been eliminated, Daya is no longer relevant, Haato never got the spotlight and no one ever mentioned her even having a stand, Norisuke and Josuke no longer shown to be close and Kyo has not had a single line of dialogue for the last 2 years.
-The manga has been setting up Jobim as the main villain, which is pathetic considering he's not threatening in the least and has no presence or charisma every Jojo villain has had.
-Yoshikage Kira was set up to be a sociopathic monster who once made a man chew off his own fingers, only for the manga to forget about this and instead make him Jotaro 2.0, erasing any bad things he could've done for the sake of him loving his mommy.
-The manga keeps dropping character motivations and plots randomly as it keeps going along as if it is being written by different people who can't keep track of who and what is supposed to do what.

I'm not saying ya can't enjoy the manga but it's a mess.
