Every once in a while, fandom is beset upon by a series of somewhat aggressive arguments about the function of accuracy in film/tv adaptations. The best of these follow my own path, which involves assessing the work on its own terms before going back to look at how it functions as an adaptation. The worst of these, however, fall into a familiar trap of damnation by comparison — typically by comparing an adaptation to fan fiction.
Essentially, the argument goes, substantial deviations from the source material make a work more fan fiction than adaptation; by doing so, these works become worse off. Fan fiction, in other words, is, by implication, a lesser form of art.
None of this, of course, is particularly surprising. While many fan fiction writers and the community which surrounds them find great value in fan fiction and its various related works (fan art, etc.), there has always been a side of the broader fan community which views such works as a lesser fan pursuit, artistically weak, or, in the most brutal rejection, contemptable garbage (sometimes verging on a kind of moral decay).
