Deletion of The Wizard of Oz book to film comparison

Comment: because there is |original research with some of the interpretations (saying the book was "undeniably darker and more violent", for example) while other comparisons are indiscriminate in saying this character/object existed in this medium, but not in that medium (per MOS:FILM#Adaptations).  An article needs to be built on |reliable, secondary sources.  If there is any attempt to add new content, merge it to the 1939 film article to show how it is different from its source material
