What aspects of some Pokémon fanfic that totally turns you off?
Here are some things that piss me off about some fics:
Trainer fics: They're too easy to write and it's often too unoriginal. I am not saying they're all crap, but many often lack a plot and stayed too closely to the game.
Using overused Pokémon: How many times do you often see trainers owning the starters, Eevee, and Pikachu? It's okay if they all have their own personalities.
Bad spelling and grammar: 'nuff said. Can't anyone use the spell and grammar check on MS Word? My fic rarely have any spelling and grammical errors because of that.
Short chapters: Annoying. Lack of beginning, middle, and end.
Scripts: VERY confusing. I can easily get lost pretty fast when I read them.
Lack of description in battles: Something like "Pikachu uses Thunder" sounds very boring. Can't writers describe the attacks?
Example: (boring) Pikachu used Thunder and shocked the Milotic out of the water.
(better) Sparks of electricity were charged up in one of Hitmonchan's gloves while at the same time dodging Tentacruel's attacking tentacles. Using the tentacles like stairs, he struck the giant jellyfish between the eyes, sending large volts of electricity throughout the entire body. (Okay, it's a little awkward, but I think you got the idea.)
Pokémon Stereotyping: Yes, I hate it when some Pokémon are stereotyped in general. For example, it totally bugs me when Fighting-types were being portrayed as stupid, brainless, and made-for-bad-guys Pokémon. Being physically strong doesn't mean being dumb. Looking cute (like Jigglypuff for example) doesn't mean ONLY girls should own them. Not all ninjas use Poison-types and so on... Think outside the box!
I'll add more...
