I find a lot of the time with the Hating Femininity Girl, it ends up being a copout. She's not interested in boys...until the right guy comes along, and then she melts! She's not interested in dresses or makeup, but still has long hair and cleans up really pretty! (Not that there's anything wrong with this, but I'd like to see a legitimately more butch woman who's totally fine with that and doesn't need to be shown the error of her ways.) I think sometimes this is a factor of having only one or two female characters in a whole work, so instead of having a few different characters with an assortment of traits, the author tries to put absolutely everything on one character. I'm also tired of the Popular People are Evil trope. Luckily, that seems to be getting subverted more often.
As for fanfic, I notice that often there'll be a few traits that are present in the main work that gets major overuse. Say a character named Sarah is mentioned as liking blueberry pie. Now in most fics, Sarah is eating blueberry pie, talking about blueberry pie, it's what she wants for her wedding cake and her first word spoken as a child. Same with overuse of jargon or nicknames where it's like the author wants to show their work, but it ends up feeling like a parody.
