Oh yeah, I definitely agree with your first two points. But I have to fall back on my own three points when I'm deciding whether or not to read a fic, doing a quick skim-through. And so much yes to this: I will backclick if there's bad dialog, because it's usually indicative of bad characterization. I find skimming through dialogue the most effective way to determine whether or not I'd want to spend time to read the fic in question. :>
