17) Really cliche plots, characters, or events. I mean, yes, sometimes it's the cliche stuff that's the most popular, but everybody's been around fan fiction long enough, at least in reading, to know what's been done. And if it will be a cliche idea, people ought to at least put a fresh spin on it. That and poor spelling or grammar, since it's so easily fixed, yet a lot of authors refuse to fix it.
18) Off the top of your head, what was the most cliche event/plot/character you've ever seen and how would you twist it to make it interesting?
