Movie Music - Good, Bad, and Bizarre

How the music of movies and television is created, and how it works (or sometimes, doesn't!) to improve our experience of movies. We look at the great movie scores - Gone With The Wind, The Big Country, Psycho and many others, from the great to the catastrophic. Is good music always good movie music (and vice versa)? Who was the most feared movie composer (and why)? How did Gone With The Wind get to be the first movie to have electronic music in its score?
