I have been reading Jojolion again from start to finish in preparation for Chapter 110 and... It's a way better read when you go through it at your own pace/not through the course of 10 years.
There's less of a gap between relevant plot threads when you don't have to wait half a year for the new big Rokakaka revelation and boring/irrelevant stuff like the Love Love Delux and Milagro Man arcs get over with pretty quickly.
Granted, some of the issues persist. Stinker arcs like Blue Lagoon still suck, but a lot of stuff that I previously found mediocre while reading monthly really shine, like the Summer Vacation arc.
Maybe it'll go on to become a better liked Part in the future, once it's done or once the anime is out in 5-6 years, who knows.
Edit so I don't double post: I gotta say tho, Wonder of You and Endless Calamity have got to be the most uneven final arcs in the entire series. There are some cool moments, but it's so full of retarded drama and asspulls it's almost rage inducing.

"Should I tho?"

"Yasuho, point the fucking phone at him!"
"Whaaa? My phone?"
