Rainey -
You mentioned your appreciation of Edith Wharton -- we have something in common, though I haven't read as much as you have. "Ethan Frome" was one of my favorite novels in high school, along with the earlier-read "To Kill A Mockingbird" -- both of which I continue to hold in high esteem.
Did you know that Wharton also wrote ghost stories? A ppbk. volume was published last year I believe -- they are supposed to be excellent! A little something to add to your reading after E.F. Benson, whom Luciaphil informed us about ...
Also, as to your curious theory about not making movies from books.
(What happened to the smilies?!!?) I've thought about my own "10 Favorite Movies" list, and it's about evenly divided as to those that are based on existing literature and those that are original as movies.
"Sense and Sensibility" ... J. Austen; "Tom Jones" ... H. Fielding; "Joseph Andrews" ... H. Fielding again; "Rebecca" ... D. du Maurier ...; "Emma" ... J. Austen again ...
But the more I think of it, even those I didn't think about at first as having literary antecedents actually do have literary antecedents ... "Vertigo" was based on a French novel; "Cabaret" was based on stories by C. Isherwood, etc.
In most cases, I agree, the book is better than the movie. But film is a different medium and has to "translate" one medim to another. Sometimes the result is alchemy!
