Amazing.
Format: Kindle
Just like a good movie, the first 10 pages = mind blown. Wow, such really, really good material here. If you're new, this will help you a ton. If you're experienced, this book will help you realize WHY great dialogue is so great, enabling you to create the magic again and again. I love how McKee covers several medias ( screen, theater, novel ) but still stays true and clear on the concept. A virtual masterclass on the subject. One of the best screenwriting books out there, and Yes, it's well worth all the hype.

So to speak
Format: Kindle
Previews did not show the Table of Contents, but it is worth searching the web for. The coverage includes practical techniques as well as case studies. Notes cover titles on topics over several decades. This book has four parts about what dialogue is, how it can mended, and how it can be created and designed. Trialogue, the third thing through which a pair of characters channel conflict in conversation, is an interesting concept because it overlaps social networks or media and comms devices; it is also looked at historically. Dialogue is reportedly the quickest way to fix a narrative text since it appeals to intuition. Those levels of depth are what the book is about. They can be found in first person voice. The approach could easily fill a site on the order of tropes for favorite titles, but for deconstruction and revision, which are also relevant to works in progress. It talks about finding characters in the dark, though not necessarily from the milieu, unless it were compressed and made to transfer meaning like in poetry, but reflexive so that it is symmetrical to the characters or human nature. If there is a boundary to be found, then this method is going to hit the lines to find out what happens then. The impact on the rest of the narrative elements is discussed. This extends back through the early philosophers, through tragedy, the merging of European roots into English, and the study of personalities to contemporary customs. Voice is plot.

ONE OF THE TWO BEST BOOKS ON SCREENWRITING
Format: Hardcover
Probably the best book on screenwriting ever (besides Egri), though there is also much here for the novelist and playwright. I am a professional TV writer, of long-standing (35 years), and I can tell you I used this book to figure out how to fix the problems of a complex pilot I'm writing; the author truly " guided me home." And lest you think I'm a McKee sycophant, I am not. I found little in STORY for me. The only thing I disagree with in DIALOGUE is that the author sells his own work short: it isn't just for those who are "lost" in their writing, like me, and the student, it's for anyone who writes fiction for a living, in any form, no matter how much experience they have. It's that good.

McKee’s best
Format: Kindle
More relevant than STORY, more useful on a daily basis. This is the book I recommend to all beginning writers. I’ve now read it three times and will read it at least three more. I learn, relearn, and remember bits and pieces each time. It is one of three books that has made me the greatest writer of all time.* *my opinion, anyway.

Incredible.....or, you know, like totally, Dazzling!
Format: Hardcover
This character and omnibus are excellent! The sturdy hardcover contains the entire original series plus additional one-shot graphic novels and guest appearances in other series. Colors look nice and well printed. The main character is a mutant singer trying to make her way in the world which adds an extra dimension to her story. The artwork is fun to look at and around 2/3 of the way through the book Dazzler gets an updated 1980s costume. How many other super heroes can take on Galactus in roller skates? Highly recommended!
