why make the novel into a film?

The novel Madame Bovary was written by Flaubert with the intention of creating a "livre sur rien" - a book about nothing. indeed, the story in the book is nothing remarkable - a bored housewife has two fruitless affairs in Normandy. what is more important in the novel is the questions Flaubert raises about the novel as a literary form - the use of irony, the flaws of realism as a means to portray reality, and the inevitable ambiguities arising from a third person narrative. everything that makes the novel interesting exists only because Flaubert chose to write it in novel form - not a poem, not a song, not a film (of course cinema didnt exist in the 19th century). it would be impossible to carry over such features into a film, simply because we lose the objectivity and ambiguity of a third person narrator in the visual medium. therefore, it seems pointless to ever make madame bovary a film - every version i have seen is dull and misinterprets the book and its story. it is not a story of romance and love - indeed it seems that Emma is simply bored rather than in love with her men. of course id love to debate this - please feel free to disagree with my comments. but i assure you that, as a student of French literature at the University of Oxford, I will know more about the original text than you.
