mischaracterization in fics

ever read a fic but a character or like multiple characters were completely ooc and it made u feel annoyed or feel mental anguish

im currently reading a fic with a sex scene and the mischaracterization in it scene was so bad i started shouting "my goat would never do this" like usually im fine with ooc bc everyone has their own interpretations of characters but even then you can at least get one thing right abt their personality
