It's good and it's big and it has sections on everything you want to know and also things you didn't realise you needed to know (like how a sound editor marks up their cue sheets). In parts the text is fluid and lucid and eminently readable; in other parts the other author must take over and it's a wishy-washy mess of uncongealed metaphoric hand-waving. The sections especially on the director's role in developing the story and how to approach directing actors are genuinely very helpful. Whenever these well-meaning elderly authors talk about technology, however, they are usually only mostly right. The discussion of mirrorless cameras or LUTs is so close to being right. But you can't blame them, they're clearly Mac users (they never talk about video files, only QuickTime files).
Having read the whole thing cover-to-cover, for some reason, I can say that the pace is brisk enough that things never get too boring. There is the usual film-teacher disdain for commercial movies, but it's not as bad as Robert McKee's. And there's just a lot of good, clear, demystifying advice about the practical and artistic expectations of what it means to direct a film of any length. To that end, this is a good text, but don't forget to augment it with genius YouTube content like In Depth Cine and MovieWise. Their examples are in colour, and move!
