Why do you DNF?

Hello all! Since I'm in a soul crushing reading slump while starting classes for next semester, starting a new job and getting far into some dramas, I find myself not being able to post as much. So I'm posing a question to anybody that still reads this blog despite my ridiculous absence.

What is the kiss of death for a book for you?

I've always tried my best to finish all the books that I start. I was very proud of myself last semester for finishing a text book cover to cover which I have never done before. Sure, I've gone through most of the chapters before but I've never just read everything, including the Appendix which had the Constitution and other things in it. But anyways, I'm in the middle of another book at the moment and I'm really thinking about not finishing it. And I asked myself why.

What makes a book so difficult or annoying or whatever to the point where you can't read a single more page?

For this one book, it's the main character. She's weak and has no real personality besides complaining. I understand her situation but in most other books, the main character has some backbone or something that drives her to be something. This girl has nothing. She's a limp noodle and so far has basically done what she has been told to do.

Oh well...fate accepted.

Another difficult thing for me to read is terrible dialogue. When authors try to do vernacular or their language is too stiff, it makes the book arduous and boring. I just want to scream that nobody really talks like that!

I'm struggling to remember other reasons why I quit reading books. Sometimes the main character or the supporting characters drive me crazy. I've quit a book before because it depicted abuse in a way that glorified it or there was excessive slut shaming, body shaming, or other types of ingrained behavior that denigrates women (or anybody for that matter. I hate bullies).

But I'm turning to y'all now. Is there anything that makes you want to hurl books across the room? I'm curious because everybody has different taste and different opinions about this.
