Bread and butter.

I will say there are a few pieces of advice that truly are more stylistic than the book would suggest. Namely the way parentheticals are used. It's probably not a *bad* idea to structure it the way it's laid out here at all, but the books "DO THIS, NOT THIS" format gets a little wonky.

It's handy. Seems like most screenwriting classes are going to prefer you own this book, so you might as well own this book.
