Living vicariously through fiction

How do you decide that a fic is "well-written"?

I see this all the time in seek comms and elsewhere- asking for "well-written" fics and well - that just seems so generic and unspecific to me. (and actually kind of pretentious too tbqh)

Is it 'well-written' because you like it? If you don't like it does that make it not well -written?

What quantifies something as well- written? Good grammar? no typos? Long, pretentious, character studies?

I judge a fic by if I enjoy it , if it makes me think , or feel (and yes horny is a feeling :P if it's hot that totally counts), but some of my very, very favorites are probably not that "well-written" in the English major kind of way. Does that matter? Not to me.

Writing complete, believable women in gay romance is more or less dancing like Ginger Rogers, who did everything Fred Astaire did, but backwards – and in high heels. It may not be easy, but it’s definitely worth the effort.

I am intrigued by THIS POST

It's sort of a pet peeve of mine (badly written, demonized women) but then, unless it's crack! I really hate "everyone on the planet is gay" fic too! How do you find your balance guys?

Also- for all you guys writing historical AU's? -The Macaronis kinda rocks.
