The Importance of a Good Plot. Monkeys with Typewriters by Scarlett Thomas

This is a series of lectures in which Scarlett Thomas studies the important features of good plots, shows the differences between tragedies and comedies, and uses examples from movies, such as Toy Story and How To Marry A Millionaire.  This is interesting and helpful for aspiring fiction writers, however, I could only read a little bit at a time.  I need to read it properly and make notes.
