(In order of reading, without seeing any other comments or spoilers.)
JJK: Somebody really HATES coming up with chapter titles.
OP: Still chaos.
BC: I was actually disappointed this chapter wasn't longer. Been a while since that happened.
Mashle: Another bad guy, with an attitude almost indistinguishable from the last. I'm bored.
OBO: Slice of life again? I guess it helps to flesh out the world, but it's not very exciti- I take that back. No wait, actually I don't. It's still not very exciting, just gratuit violence for the sake of shock. It doesn't even work to make the bad guys interesting.
Phantom Seer: ... I want to read that Sherlock Holmes spin-off. This is a series where I dislike most of the characters at first sight, but then change my mind about them as soon as I get to know them a little better. Really digging the mystery plot, too.
Dr Stone: Chrome being happy for Senku is the cutest thing. Boichi is a genius, being able to convey so much subtlety with just his art. And so is Inagaki, because this chapter of nothing but talking didn't bore me for a second.
UU: Whaa..? I mean, it's not that it isn't interesting, but that was a little too meta for me. (I guess they got really annoyed by people pronouncing the title wrong? But seriously, I'm getting Time Paradox Ghost Writer vibes here.) I also don't get the point, I mean, if you wanted to see the raws, why not just send a spy in there? You have a entire team of people with magical powers, this shouldn't be so hard. I don't mind an inside joke at times, but not when it feels like it's derailing the plot.
Cop & dolphin: I don't remember who half of these characters are and I don't care enough to look it up. But I hope we'll be getting an explanation for why the dolphins are helping the guy with the most boring motive ever.
WNL: ... Why do people like this character...? Nevermind, it's almost over anyway.
High school family: This is sad. Reading this makes me feel sad. I feel bad for everyone in this series.
Me & Roboco: Another one? How did we end up with 3 Undead x Unluck manga in the same issue? And the TPGW vibes are even stronger here. Though I sorta gotta admire Jump for being okay with this level of self-mockery.
Moriking: What's with the references this week?! Was it Jump week or something? Was everyone encouraged to work Jump and its history into their manga somehow? They're not even trying to be subtle about it.
Magu-chan: Trope, trope, trope, trope, product placement, trope. Jump week it is.
AG: It was funny for, like, two pages.
Yozakura: Kind of disappointing after last chapter. The mystery is all gone, the father plot falls flat and Taiyo is completely on the defensive. What a shame.
AT: Another common trope story. Only this time I don't think it was the intent.
