Revamped/redone stories
Analyze why certain things are redone over and over again. For example, why is Romeo and Juliet so popular that it is re-released in different formats? These include: movies, books, parodies, revamped novels/movies/games, etc. Why are fairy tales re-written every couple of years? Why are certain movies redone and re-released every few years? It can't just be popularity, is there a trend in the stories?
