I drop series if I can foresee what's to come.
This phenomenon is caused by an unoriginal plot,
clichés and simple/stereotypical/overused character
personalities. I never drop series even if it takes
9 months for a chapter to come out. There's too much
trash out there for me to sacrifice a good series.
I've sometimes dropped a series if the characters
have annoyed me to the core with their puny problems
that I could solve in 5 minutes when they bleed and
grieve with them for seven arcs with sixteen chapters
and I am supposed to follow their lamentation and
brush my nasolacrimal ducts in fervor.

Some of the characters can be annoying of course.
After all, there are a lot of annoying people out there,
but instead of listening to their annoying mouths and
looking at their annoying faces, I can just walk away
if I don't feel like wasting my time with them.
This works with manga as well.

I will get into a manga at one time, and read every chapter out. Then after a week r two stop reading it altogether. I think it's that I get into certain kind of story for a bit, then after I'm out of that groove, not want anything to do with it.

Maybe I'm fickle?
I have dropped a few series but don't remember them exactly.
The reason of why I drop them its because:
1)The plot becomes predictable; the plot never ends...and you can start seeing a pattern in it.
2)The characters underdevelop. Yes, instead of them becoming more developed then stop and reverse back. DX
3) If the art doesn't improve as the plot continues. I like to see some improvements on the mangaka.
4)If I like the manga, I'd want to buy it myself so in order to not spoil myself I stop reading before it ends. XD Yes, it doesn't matter if the ending ins't good, I just don't spoil myself. XD

To me it doesn't matter if the manga goes until 1000 chapters, but it better not keep on repeating itself. =__=;

I drop a series when the stuff gets repetitive, like most generic shounen manga where new enemies pop out of no where after the previous ones die.

I also drop a series in shoujo when the girl will most likely not go for the guy I prefer. >_<

I dropped a couple series cuz outta nowhere while reading it updates for every other series i read come out and new manga titles come out so i end up reading those and forgetting the manga i was previously reading lol

bad art, bad plot, hates characters<--those are some reasons I drop manga. But i never drop a manga because the releases are slow. I drop it when i feel that it's uninteresting or boring.

Ive never dropped a manga, and i love really long ones over 200+ chapters, like Hajime no Ippo, 879 and ongoing baby xD, i would probably only drop a manga if its super shoujo. but if its shoujo i usually dont even start it unless its under 30 chapters xD

Generic Manga Lover ^o^, taking all suggestions on new series.

I'll drop a manga that disappoints me in some way - story becomes too corny/predictable despite an originally good premise, characters become weak/dweeby/unrealistic despite originally interesting traits, etc. Weirdly enough if I start off a manga knowing it's predictable/trashy, I'll still stick with it. Lol. It's the disappointment factor that makes me give up... It's like some kind of betrayal, idk...

I totally agree with whatever Harukko said. 🙂

Nope. It takes a lot for me to drop a series, and often I end up reading chapters worth of something I consider rubbish 🤢

I don't care what people think about what I read. I certainly would never drop a series because of that!

Why would someone bump a two year old thread, especially one like this?
Well anyway, I've only dropped a handful of series, cos I'm picky in the initial selection phase. What I decide to read usually turns out to be worth keeping up...
