We get a film , or a book , and we want more , and if we do not get more , we write fanfiction . I know this is not exactly a thing that begun in the XXth century , but I think that Tolkien and Tezuka are two of the key authors that helped turn the world of entertainment into what it is today . There are , of course , lots of differences as well . Their mindsets could not be more different .
