Little Things That BUG Me #2

Media (movies, books, etc), whose stories offer "morals" that have already received near universal acceptance by society before the work was written. Gee, District 9, apartheid is bad? You know, South African society kind of figured that out about a decade before the short film that was later expanded into the movie bothered to tell them but thanks anyway. Sure it took them long enough but delivering sermons that far after the fact just bugs me.
