Complaining about swearing and then swearing? I sense irony lol.
Your reading experience seems to be plagued by memories of other bad manga. The art was quite rough, but like you yourself said, there is potential. For me, more potential than everyone else. I didn't know they submitted it in english, I thought it was translated. If you hate it on a personal level, then it's really just your opinion. Sorry for my two cents.
You really liked Sweat Man more than Morning Star?
Believe it or not, I am not a shonen comic. I can swear in this instance without it being irony (though if you want an example of how I hold true, the podcast where I explicitly explore Weekly Shonen Jump titles is deliberately curse-free, to be appropriate to the subject matter).
My experience was mostly plagued by a shit one-shot, but yeah, it is just my opinion. Gonna blow your mind here, all judgement by a singular person is personal. That's a given. Objectively there are probably nicer things I could say about it, sure, but I think even then it wouldn't be very good.
Sweat man though…. Yeah, I liked it more, but I didn't really like it much at all. The concept was strong, the plot itself could have worked, but the execution was poor, the ending didn't really work for me and it felt like there was too much of a dissonance in the art between the protagonist and the... sidekick, i guess i'd call him. Not to mention the slightly worrying gay gag (redeemed slightly by it not being about that as much as that he'd get given too much attention and his sweaty secret would be revealed, which was kinda a funny train of thought). But yeah, importantly, I came away from Sweat Man feeling like I'd gained something from the experience. Morning Star didn't accomplish that.
Also don't apologise for your two cents, it makes for an interesting discussion at the least.
