On the other hand, there have been instances when not-so-great novels have been transformed into great movies.Mario Puzo's The its godfather was quite popular at the time of its release as a novel,but critics hailed it more for its entertainment value than for its value as literature. the film adaptation of this popular novel,however,continues to be listed among the top ten greatest movies of all time. Likewise, the science fiction short story "Do Androids Dream of Electric Sheep?" did not set the science fiction genre on fire when it came out. The movie version, though, made a much bigger impact in its medium. Today,Blade Runner continues to top critics'lists of great films.
