Not too bad!!
This is a good book if you want an over view of how to get started. There are lots of tips and facts that will help you start your masterpiece. This book doesn't really go into great detail about crafting your main characters or sub characters, conflicts or plot points or story arcs. I read a good book from the teach yourself range called 'Screenwriting', this is good for the 3 act structure, conflicts, set ups, set backs and climaxes, it really helps with character development in all aspects.
