Ginny tends to get a raw deal-- she's usually either way-too-perfect author insert or whiny annoyance even in fic that *likes* her, which of course just inspires other people to torture her.

But also, in *canon*, she spent a year being emotionally abused, tortured and brainwashed by the most evil wizard of the century, while nobody who was supposed to be watching over her even noticed, and afterward she ... got scolded for being careless and then was expected to pretend it had never happened, and be perky happy girl, just like everyone else was pretending? Good Ginny fic has to deal with that somehow, and yeah it tends to get pretty dark!
