The question of why a writer can make the words on the page come to felt life in one genre but not another--why the gift of expressiveness is extended here while that of appreciation goes there--this question remains unanswerable. For the reader, it is only necessary that gift there be--the one that makes us feel alive to literature and ourselves when subject, writer, and form are brilliantly matched.
