there are many components of this book i find helpful for conceiving and executing a screenplay. first of these chronologically is its discussion of the logline, which is the brief one or two sentence descriptor given for a title of movie either in an ad or on a title screen for streaming. next, while i dont believe it is applicable for all screenplays to the letter, i appreciate the template the author provides for writing a screenplay, with the individual aspects of this template being discussed in more detail in following sections. out of the describing sections, i find most helpful that of the first and last 10 pages of the script, and how these sections reflect a change, almost to the effect of an opposite pole, within a successful script. i also like the sections discussing the importance of turning points, both between act 1 and 2, along with that between act 2 and 3, occurring with the former around page 25 and the latter around page 75. further, to backtrack some within the sequence of the book, the author also lists some categories all movie scripts might be assigned, with some difference between these categories he suggests and traditional movie genres. that said, i dont find these distinctions he makes particularly helpful anymore than standard movie genre distinctions. i also find the majority of references to movie scripts made in this book to be out of date. thus, although this book contains several helpful recommendations for an aspiring screenwriter, including the titular section about the importance of writing scenes to secure character likeability, a la cat from a tree, it is not a must-read or definitive book for writers in this position, in my opinion.
