The main thing to say about this book is that it's repetitive. Really, really repetitive. Phenomenally repetitive. You think the start of this review is repetitive? No, my friend. Compared to the book, my review is not remotely repetitive.
Sentences are repeated. Quotes are repeated. Advice is repeated ad infinitum. The book has 308 pages without the index. I reckon you could boil that down to less than half the size if you just took out all the bits that are said more than once. You may find this hard to believe but there are things in here that are repeated more than four times.
So why do I still give it four stars?
Well, I think the repetition works. OK, it goes a little too far on that point. And there will be some readers (though none who can argue I haven't done my utmost to warn them) who get really worn down by the repetition. But for me, since this is only my second screenwriting book and I haven't been to any classes, I have probably benefited from the repetition.
It really hammers its points home. If you don't remember the main points after being told again and again and again, then when will you learn them?
So this book is like being taught by a teacher who doesn't trust you to remember the key points. He hits you over the head with them. Then again. Then again. And then one more time, just to be sure.
In my case, it's probably a good thing that he does. For other people, though, it may be much too much.
