Oh yeah, if the comedy isn't hitting, then it should be dropped. As much I love the series and how well Kenta uses the comedy for build up for the more serious moments in the series. If the comedy isn't hitting, there really is no point in watching it since it is a Gag Comedy at its core.
Though it probably is the best romance in Jump after Dandadan. That aspect is very well done.
Tbh, let's say we cut out the romance and SoL stuff with the cast. (Which is literally the reason to watch and read the series)
The action stuff is still pretty solid. A lot like CSM, Dandadan uses show rather than tell regarding the characters and their abilities. I fukking hate shounen exposition, like I really start to detest it. Kind of why I love early JJK because it felt so much more concise than what it became later on. Though again, like others said, you are literally cutting out the main appeal of Dandadan if you cut out the Romance & SoL stuff
Gachikuta I like a lot, but I can't lie that it hits a lot of the generic bits. Though the power system is great and creative in execution. I do think Bones is hard carrying the anime, but I think there is enough to stick with it, unlike those other 2.
Kaiju 8 & Tougen Anki are like a full-on checklist of shounen tropes and all the generic stuff where it's like, Man, the author mailed it in. Why would I watch those when I can just watch Solo Leveling at that point? Even though Solo Leveling is very shounen in terms of writing, it feels different at least. Probably has to do with the fact that it is a Korean series. (Never though I would be advocating for Solo Leveling, but here I am doing that, I guess

)
