Reddit reviews The Art of Dramatic Writing: Its Basis in the Creative Interpretation of Human Motives

Seriously, get Vogler's The Writer's Journey. It is much more practical, open-ended and inspiring than Save the Cat. It's based off of the ideas of Joseph Campbell, whose worke inspired Star Wars. It is a much more classic and legitimate structure than Save the Cat, and yet it is a series of guidelines, not hard-pressed rules. Blake Snyder in his book basically says if you deviate from my formula, you suck. The dude even hates Memento.

Or read Lajos Egri's The Art of Dramatic Writing. It seems your problem is that you don't have a defined character with hopes, goals, worst nightmares and biggest weaknesses. That should be the starting point of any script: your character. This book opens you up to finding out what you value about your character and how to build them for dramatic conflict. Its a revelation for someone who hasn't thought of story as character arcs and dramatic progression.
