FanFiction

So somethings I'm going to list I feel are outright bad writing, but considering how popular such stories are I'm going to list it anyways because it's clearly not a universal opinion. (To further note, these are things I apply to both original and fanfic.)

Green Aesop styled stories that treat humans as if they aren't animals and don't also come from nature. That they are all inherently evil. It completely disregards how most damage isn't from majority of humanity but billionaires. It's also massively ablest. If it doesn't disregard, it outright states that if you don't have a body that that handle being in the wild, fuck you.

That is, unless the work has decided to go, "nature is innocent" route. How to instantly tell me you have never worked with animals, done anything in nature, or know anyone who has. Yes, there are wild animals that will help those outside their species. But don't ignore how there are there are animals that will kill not to eat- but just for fun. Some of those animals are the same species as the ones who will seek to help.

On that theme, but I don't think aren't bad writing in general. Just massively poorly categorised by people who like staying genre-blind (and this complaint is largely aimed at fan works and specifically a certain fandom):

Works that take the high-fantasy setting, claim its going to deconstruct and show how certain things would be applied realistically... but what they actually mean is they want to write grimdark with no research. All the wild animals basically act the same regardless of their inspired background. Turned into common house cats or sport dog breeds. That is, if they aren't just humans in fursuits.

Wanting to tell stories like this isn't bad, just, dammit, be honest about what you actually want to write? This misinformation is so bad that in this same fandom people often say my work is grimdark.

One I admit isn't bad writing and is a pure pet peeve: Characters who know who caused them harm but lash out and deliberately hurt others who were not involved. This is something that happens all the time in reality. But I really, really cannot stand it in fiction. (There is only one story exception I have but to explain will make this post extra long and it's already 9+ paragraphs hhhhh)

One similar vibe: "no one understands me!" or, "you don't get it" by a character who never tried to explain what was going on. Extra points when this is yelled at someone who is completely new to the situation. Like? No shit they don't know? Why are you talking as if they have been in this situation as long as you have?

Stories that are more deeply invested in describing the look of every room and outfit instead of moving the plot forward. I'd might be able to forgive it if it was a Locked-Room Mystery or similar, but that has not been my luck. A big warning to me is when authors phrase celebrations entirely around their wordcount. Instead of what exactly that wordcount accomplished.
