Scriptwriting is a great all purpose review of both the creative and business sides of writing for TV, movies, animation, radio drama, and the stage. Straczynski is the perfect authority to write on these subjects, having garnered success in all those fields.
The book is a how to manual, with plenty of examples to follow. It also traces out the business side of selling what you write. Straczynski writes in a personable style, but pulls no punches. He helps a potentional writer separate his dreams from reality without crushing one's ambition. This book has been used in colleges as a textbook and upon reading it, yu'll see why. It's a handy reference tool that I have thumbed back through scores of times over the last 3 years. I give it the highest praise. It should be the starting point for anyone serious about writing in the performing arts.
