What is the things that makes you dropped what your currently reading

For the manhwa for example is the art. If I don't like the art or I will considered it us "ugly" I will literally dropped it ooof except if the story or the plot is likeable then I'll stay for the mean time tho I feel sorry for the artist or the auther since ik they work hard on it.For the readings like novels is that the fl or the ml talked too much by his/herself, I mean when he's not talking to other characters you know? Sorry I'm not good at this language nor explaining things. So what's yours? I'm quiet curious.
