This book is very good at hitting the different things that make a screenplay interesting and successful, but it also repeats itself a LOT. Not just with the information it tells you, but says the same issue is caused by different things. Here's an example: In one chapter, it says that if your screenplay is not exciting, it's probably the lack of suspense. Then in another chapter, it says if it's slow or unexciting, it's due to the dialogue. This repeats itself throughout the book. I liked the advice for the most part, but this was frustrating, because I didn't know where to look to solve my problems because it told me if my screenplay is X, it's because of A, B, C, D, E, F, and G all at once.
