Fan Casting Truer to the Text in Sort by Tropes

If a book or comic becomes sufficiently popular, it will almost definitely get a TV show or a movie. While some fans rejoice upon hearing that their favorite series is getting an adaptation, all too often a contingent of the fanbase will find themselves miffed about changes to the work that the general public might not care too much about, and consider that a part of what made the original great is missing. The problems are especially likely to surface when the story is ongoing and the staff has to work with incomplete source material. The usual result of such circumstances is a Broken Base.
