A fun overview of writing for different media and genre. Ashton takes great care to explain the differences between movies, tv, stage, and radio writing, as well as the challenges and opportunities for each. He also provides multiple examples from relatively recent series, films, etc., in order to illustrate his points. It was a helpful book.
With that said, I wish he would have included some material on things like formatting, staging considerations, and the like. It would have helped newbie writers who are trying to make that special script that will get them noticed.
