Gosh, I thought of myself as an all-eater with a few personal dislikes, but reading this thread, I totally see now how picky I can be tho)))
Honestly, I tend to finish the book (classic or webnovel). I've developed the ability to drop and move on only recently, when figured out how much fun stuff I could do instead. And it was pretty hard to remember all the main reasons why I did close them without finishing. And, of course, there are few that I regret I didn't drop.
Things like bad grammar or poor writing - I guess it's common for most of the readers not to spend their time for some averagely composed text. I saw young authors try defending themselves like "if there's a great plot beneath, who cares about the grammar". Well, I also heard this very precise saying that "Reading a novel written with mistakes is like watching a movie with a poor signal on TV with interference, noises etc. It may be the best movie of the year, but I'm not gonna watch it with the quality that low that I cannot concentrate on the plot."
Abusive relationship, including all the scopes of BDSM.
Someone mentioned here this 50 shades of garbage. I did read that just to have the right to legitimately shame and hate it, while feeling nearly like vomiting until I reached the end..
Like, gurls... we've been considered a trash, non-humans that are exist only to breed, and the lowest social rank for like ... forever! And still are, I can't see the future where women get real respect and equality... And you fetishize/romanticize christian gray??? ffs! Plus.. it was sooo poorly written that hot scenes were rather ew.. :shivers:
Not only girls, to be fair, I will drop the BL where the top is forcing his kinks of humiliation, body punishment and other abusory on the bottom who is not into BDSM originally (but wants to please the top -- that's the worse!). Generally, if the BDSM thematic is forced - I'll pass.
I get it if the couple is into it and if the text shows that their bodies, hearts, and souls need that... fine.. let it be. But that's not my cup of tea either.. like... no punishment or self-harm. My body is sacred and there is no pleasure in pain, only tears, fear and hate towards the person who inflicted it, but that's my vision..
No abuse, no violence in relationships, no Killing Stalking... thanks but no thanks. I hear a lot lately that with writing/reading such content people try to deal with their traumas. If that is true, that's really great. But I'll feel sad if in reality it doesn't help and they write it only due to some weird kind of mainstream.
Isekai/Accidental travel/эти чертовы попаданцы is a NO for me. I've read a lot of them when I started introducing myself to online novels, and boy, that was a relief to find out that there are stories other than that. What puts me off especially is their attitude when they arrive to the new world.. you know.. and if they are the chosen ones and foreseen to come to this world and save it... MEH. However, I'm cool with some reborn-into-the-same-world in the same or other body, same or other timelapse. I mean.. not the most welcomed trope but it did work for me in certain cases, Chinese xianxia danmei f.e.)))) So it still depends.
Total misunderstanding. I mean.. when treated cautiously, it can be a win, but when NOBODY tells ANYTHING they SHOULD've been in normal setting, and all that is happening in the novel/comic is a cobweb of unspoken facts, or evasiveness, or lies because of jealousy and there's no one to tell MC what the truth was etc. - hell no.
Omegaverse the way they usually put it. I have read a few, but only one author could show it in a way that wasn't repulsing for me to read. And.. well, I must confess I also have written an o-verse, trying to evade those sickening clichés that I dislike, but I haven't tick that box in the novel/comic search when looking for some reading material for a very long time. But generally, I find male pregnancy appealing... endearing even))) Or not pregnancy but fatherhood smh.
Too much sex - plot what plot. Being an active NSFW reader and writer, I prefer UST, hints, touches etc. to porn in every chapter. There has to be attraction evolution, tension building... c'mon)) One sex scene for a novel that is well elaborated, or even no NSFW at all is better than too much of it.
Too much depression. I really really really don't like when everything is bad and get's worse and everybody dies... Another thing I regret I didn't drop is 1984. It hurt me to read because we still scrambling out of that state of affairs here in the Post-Soviet area and.... I'd rather read too much sex than that. There's a lot of dark tropes in real life, so plz give me something to smile upon while reading. Again, I like to read horrors once in a while, mystery and mistic, gore action even (#thankyouisayama), and I'm head over heels after good puzzled crime novels... but the villain must be neutralized in the end.
That's all I could compile in one sitting. But honestly, it's a list of deal-brakers within that scope of genres I generally read. And there are plenty of stuff I don't read and never even look at that directions like harems, damsels in distress, school or student life (that implies teens), something that may seem like a good romance (straight or BL) and then shifts to sickeningly sweet fluff with hearts and bubbles.
