This is an extremely useful book if you want to learn how to write for television dramas. (It's use is limited if you want to write sitcoms because the author specializes in dramatic series.) There are good examples of script pages, including the opening pages of episodes from the great series "NYPD Blue." Pamela Douglas analyzes these, although, like a strict teacher, she sometimes explicitly says she isn't going to spoonfeed the analysis to you; you must figure out some things for yourself.
There are plenty of quotes from and interviews with well-known scriptwriters, presentations of dramatic techniques (although the author assumes the reader has learned something about that already), and an account of the complicated and highly involved process by which a television series goes from an idea to a successful series--or a failed one.
Most pertinent are explanations of the process of "breaking" a story for a television show with commercials approximately every ten to fifteen minutes. Did you ever wonder how they figure out how to put a mini-cliffhanger just before each commercial break?
Douglas is a somewhat off-handed person. She tells a story on herself of how she changed the ending of a story without consulting the producer and learned not to do that again. Many would have gone in knowing not to do that, but I suspect that people who substitute their own ideas for those of others thrive particularly in Hollywood. (See my review of "Set up, Joke, Set up, Joke," a novel about sitcom writing.)
Another example of Douglas's offhandedness is her way of sometimes misrepresenting things without meaning to do anything malicious. For example, early in this book, she describes a series she worked on very briefly early in her career. She describes the setting of the show incorrectly. So what, though? She admittedly only worked on it briefly and long ago. So why should she have to be accurate? Well, because this is a college text book that has gone through a few editions, and committing a book to publication should imply some responsibility for accuracy.
Another thing I would wish for is more of an explanation of the meanings of the terms "tone" and "style," but I suppose that is knowledge one should have already mastered before coming to this book.
Quibbling aside, this is a very useful book that has actually inspired me to work on an idea I have for a television series. I have gotten as far as writing a format (something explained in this book), making rough outlines of episodes and thinking about where this series of mine might fit in the television universe. (Best fit would be AMC, I think.) In any case, I have not finished reading the book, so maybe I'll be inspired to write a pilot script, too.
