I think my primary reason for dropping a series is when the characters just become Mary Sues or just brats. I think having a main character after so many chapters becoming unlikable because either:
-> They are perfect in every aspect
- every time they do something bad, they are instantly forgiven or get away with it
- every character is in love with them (excluding harem-focused series)
- never make any mistakes
- side characters are usually also Mary Sues
-> Character complains about everything
- character is angsty af and just turns into whining
- despite people doing good things for them, they just continue to be angsty
- I can understand depression and whatnot - but it usually turns into a pity-party
It's really unfortunate because people here have great art, but their series turns very Mary Sue so quickly. I know people want to praise their main character, but having no flaws is a complete turn-off for me.
