good thing you thought shibuya was bad bc the manga falls off HARD during culling games.I genuinely hate the Shibuya Arc and it's where I quit JJK
I hate how things just happen. Why does Toji come back? He doesn't do shit except look cool and then dying before giving Megumi a single fucking interesting interaction
I hated the Mahoraga reveal so much. Megumi feels genuinely like the author's punching bag, he never gets cool shit to do besides his incomplete domain expansion, always gets punished psychologically and physically and with the reveal that he has Mahoraga, it was also revealed that he was willing to commit suicide at several points before this arc, some of these points being minor obstacles for almost every character except for Megumi
I don't get why characters die in JJK without doing anything before they die and then still being forced into the story somehow. Mechamaru was introduced and killed it off within a single fight, yet everything plot-relevant he does is past his death
I hated the Kenjaku reveal. Geto was the most interesting character in the story and again, the most important thing he does is be a vessel for a much, much less interesting villain, past his death
There's a lot of small points I found bad to awful. Nanami is one of the best characters in the story, the moment he punched Taylor Swift to death was cool. But Taylor Swift didn't die. He just bullied Megumi again after Megumi's father committed suicide in front of him. Did I mention how much I fucking hate how bad Megumi was treated? I don't even love Megumi particularly, but the punishment he receives throughout JJK is comparable to what Squidward goes through in modern SpongeBob episodes
Sukuna is legit trash. There was Geto who was well-written. Sukuna is just some dude who likes to kill people. And he's somehow the most important person in the entire story. Nothing about him is interesting. I don't feel anything seeing him. Just slight annoyance and some boredom
Nobara was killed before she got to do much. Mahito is also much less interesting in Shibuya, compared to how philosophical and enticing he seemed in the Junpei arc. Again, he's like Sukuna, just a guy that kills people for fun.
I don't know man. I just hate JJK. It's incompetent and (most likely involuntarily) extremely mean-spirited. The dissapointment from JJK and MHA years prior has led me to stop following shonen
CG arc has pretty much all the issues you mentioned with shibuya except all the important character moments fall even flatter compared to their pre-CG counterparts that gege was clearly trying to mimic because they opted to replace the original (barely) slice-of-lifey aspects that actually develop and make us interested in the characters with constant, nonstop balls-to-the-walls action that serves zero narrative purpose other than making the important characters look badass.
