reading very long stories makes flaws in the diversity of character behaviors, spoken phrases and other individual written character flaws or quirks more apparent.
Having multiple different characters act and feel differently is hard for the writer. It is harder for the reader if from-the-norm-behavior is multiplied to most of the individual characters and the lack of diversity in in character interaction responses is equally bad.
A set of characters changes a spoken word that is not normally used in everyday interaction.
When a set of characters use the made up word "goddongit" instead of "goddammit" I can maybe interpret it as a reader, that the family has a rule to use that word or it is a local slang. But if every character uses that word even if they never met the family and are in a different state than it's grating.
Could be that the author uses it to censor swear words but I don't see the point in a story about sex, rape and murder.
(and overall cant wrap my head around why US people have issues with harmless words like "damn it" or "oh god")
When the characters only have singular interaction responses.
I was shaking my head after the hundredth use of "flipped the bird to xyz" in one story about teenagers. Yes, teenagers are prone to "flip the bird", but as the ONLY response? From every character?
No "rolling eyes", "snarls", witty responses? Although, "rolling eyes" is another candidate for overuse in stories. If every character has the same response to interactions than they feel more like clones.
Character descriptive phrases.
In one story I read the phrase "Thinks of himself as god's gift to woman" from 3 or 4 different characters describe a dozen different male assholes as "thinks himself of gods gift to woman".
I can understand if it is only 1 character who uses the phrase, thats their character quirk etc. But when 3 or 4 different character uses the phrase (who didnt even met at that point) it is jarring.
Maybe use other descriptions, i.e. "misogynistic asshole" or something.
What are other examples?
